CGC Census: Grades For The 1960s

Continuing the thoughts of a previous post, let’s take a moment to focus on the 1960s. Comparing the CGC Census grades (cumulative percentages for Universal and Signature Series), we see a distinct difference between the decade and the most valuable comic book in the decade, Amazing Fantasy #15 (1962).

These differences are due to two major factors, first, that books submitted to CGC must (generally) be worth the cost of CGC grading, otherwise, there is no financial reason to submit a book to CGC. As a result, the books submitted to CGC from 1960-1969 have primarily been higher grade copies than average, since value increases as the condition increases. Secondly, the entire decade of the 1960s has been combined to create the 1960s line on the graphic, while Amazing Fantasy #15 represents only a single issue from the single year of 1962.

To remedy these differences, the graphic below represents each year of the 1960s separately, and shows additional comics besides Amazing Fantasy #15 from 1962.

CGC Submissions (Universal and Signature Series) for each year of the 1960s, with selected comics from the early 1960s.

This may be the first time that the consistency of CGC grade percentages has been isolated for major comics of the early 1960s. Because each of these comic books (Brave & The Bold #28, Amazing Fantasy #15, Incredible Hulk #1, and Amazing Spider-Man #1) is generally worth submitting to CGC in all possible grades, these books generally reflect the full populations for each book (percentage-wise), despite every copy not being CGC graded.

While every copy of a comic book is unlikely to be sent to CGC for grading, those comics which are valuable in all grades, including valuable for the difference between CGC 0.5 and CGC 1.0, will be reflected on the CGC Census as a better sample of the total population of comics for that year, or possibly, for several years in that range.

It should be surprising that the four books selected are so closely aligned in their CGC grade percentages, and that they are so far from the percentages of the years they represent. It is possible that these grades may be generally applicable for all comic books of this era, CGC graded or not, even for other comic books of the same age which may have little value.

CGC Submissions (Universal and Signature Series) for Early 1960s Key Issues – Brave & The Bold #28, Amazing Fantasy #15, Incredible Hulk #1, and Amazing Spider-Man #1

Apart from more CGC 8.0 Brave and the Bold #28 than what might be expected (perhaps due to regrading), is it possible that this general distribution could be applicable to all comics from the early 1960s?

Perhaps time will tell…

CGC Census: Grades by Decade

After nearly 20 years of CGC grading (2000-2019), it is possible to see the percentages of grades assigned to comic books broken out by the ages of the comics (decades).

Cumulative Percentage of CGC Submissions By Grade Per Comic Decade (Universal and Signature only)

The graphic above shows that the percentage of higher grades decrease as the comic books get older, as we would expect, however the graphic does not accurately represent all comic books in existence. For example, judging from the numbers shown, it could be assumed that 49% of comic books from the 1960s are CGC 8.0 or higher.

However, assuming that 49% of comic books from the 1960s are CGC 8.0 or higher is not even close to accurate. What the 49% represents is that 49% of comic books from the 1960s which have been graded by CGC have been 8.0 or higher. The key factor is that these books have been graded by CGC, that is, someone selected the books to be graded, prepared the books for grading, and paid the costs of grading. There are many comic books for which CGC grading is hard to justify, due to the costs of CGC grading.

While any comic book can be graded by CGC, it is hard to understand why someone might pay $27, not including the costs of shipping, to have CGC grade and encapsulate comics which do not sell for at least $27. Most comic books do not sell for $27, including comic books from the 1960s, due to the condition of the comic or the lack of demand in the marketplace.

In order to better understand the condition of comic books from the 1960s, it would make sense to evaluate the CGC grades for comic books where all copies (regardless of condition) are worth submitting to CGC for grading. This scenario is most likely to occur with the highest valued comic books, where the difference in prices between even a CGC 0.5 and a CGC 1.0 are higher than the cost of CGC grading. For those comic books, the percentages of each CGC grade are a better representation (sample) of all copies in existence, rather than just the comics that are “CGC-worthy”.

Comparison of Cumulative Percentage of CGC Submissions By Grade for the 1960s against Amazing Fantasy #15 (1962)

The difference is staggering. Rather than expecting 49% of comic books from the 1960s to be CGC 8.0 or higher, it can be seen that only 3% of copies of Amazing Fantasy #15 (1962) have been CGC 8.0 or higher. While we should not expect every comic book from the 1960s to have the same percentages, it is reasonable to expect that Marvel comics from 1962 would be quite similar to the grades for Amazing Fantasy #15, if all copies (regardless of condition) were submitted to CGC for grading. Rather than expect 8.0 to be the average condition for comics from the 1960s, it might be safer to expect to find half of all copies no better than 3.5 to 4.0.

While there is no way to know the percentages for each grade for every comic book in existence, we can get a better representation of what may be in existence by studying the CGC Census for comic books which are “CGC-worthy” (that is, justifiable of the CGC costs, regardless of condition) as the representative for comics of the same age with similar distributions and histories. Future articles on this website will examine other comics for which every copy is worthy of submitting to CGC, regardless of condition.

One thing to note: Because these are percentages, this entire article makes no mention or estimate for the actual number of each comic still in existence. This evaluation is reflecting the percentages of each grade, whether there are 100 or 1,000,000 copies.

Overstreet Market Report – December 2018 OSPG #49

The following post contains the Overstreet Market Report supplied to the Overstreet Comic Book Price Guide #49, published in July 2019.

Despite the increasing attention placed upon slabs (third party professionally graded and encapsulated comic books), it is the raw (ungraded, non-slabbed) comic books which remain the overwhelming majority of comic books in existence, available for purchase, and sold each year. Price guides such as this one remain extremely important to the market by providing accurate listings and values for raw comics, if for no other reason than the immense size of the raw comic market this guide serves. Slabs represent a very small percentage of all comic books in existence, however, the slabbed comic market represents a much larger percentage of total dollars spent annually, particularly for the highest valued (and highest publicity key issue) comic books in each decade. The largest of the professional grading companies for comic books has been Certified Guaranty Company (CGC) since opening to the public in 2000. With CGC permission, I have been compiling the CGC census into a searchable database online since 2003. If any other grading companies also make their census information available and give permission, they will be included in future reports. While there are billions of comic books in existence, 4,161,087 comic books were reported as having been professionally graded and encapsulated according to the official CGC census by mid-December 2018. The counts break out as: 3,405,568 universal grades, 659,200 signature series, 53,488 restored, and 42,831 qualified grades. Those 4,161,087 slabs are for 179,409 different comic books, seeming to show that the average comic book sent to CGC has been graded 23 times. In fact, more than 50,000 different comics have been graded only once, more than half of the 179,409 comics have been graded three times or less, and more than 129,000 (72%) of the 179,409 have been graded fewer than ten times. Only 4% of comic books sent to CGC have been graded at least 100 times. The nine most submitted comic books to date have been graded at least 10,000 times. This might seem like a very high number of copies graded, but even 10,000 is only 10% if the print run was 100,000 comics.  The comics in the top most submitted were printed in multiple hundreds of thousands of copies. The most often CGC graded comic book is Amazing Spider-Man #300 with more than 18,000 copies graded, followed by New Mutants #98, and Wolverine Limited Series #1. The next five are Marvel Super Heroes Secret Wars #8, Uncanny X-Men #266, Incredible Hulk #181, Amazing Spider-Man #361, and Amazing Spider-Man #129. In ninth place is Spawn #1, followed by Amazing Spider-Man #252 in tenth, which is likely to exceed 10,000 graded copies by the time of this publication.  Nine of the top ten most submitted books are from Marvel, plus Spawn #1 from Image Comics.  The top most submitted comic from D.C. Comics is Batman: The Killing Joke at 17th most submitted with 5,770 copies on the CGC census.  All the Top 100 most-submitted comics are from Marvel (85), D.C. Comics (11), or Image (4). The first book represented by another publisher is Rai #0 (1992) from Valiant Comics at position #101 (2,512 copies graded).  The Top 100 most-submitted books to CGC represent 476,015 copies on the CGC census, which is 11.4% of all CGC graded comics.  The Top 1% of comics submitted to CGC (1,794 different comics) represent 1,715,163 slabs, or 41% of all slabs. 

CGC Census Counts by Comic Decade (as of mid-December 2018):

1930s = 8,254 (0.2%) –

1940s = 138,426 (3.3%) –

1950s = 135,854 (3.3%) –

1960s = 656,900 (15.8%) –

1970s = 694,187 (16.7%) –

1980s = 639,429 (15.4%) –

1990s = 472,865 (11.4%) –

2000s = 519,093 (12.5%) –

2010s = 893,984 (21.5%) –

Others = 2,095 (<0.1%) –

Total = 4,161,087.

Drawing broad conclusions using the CGC census information is more problematic than simply calculating the numbers. CGC counts, totals, and averages do not necessarily represent a sample of the whole comic book market. Comics which are sent to CGC have often been selected by the submitter for exceptional qualities of high grade condition, high market value, or both. By definition, the average raw comic is unlikely to be exceptional.  Another important note is that comics which have few copies on the CGC census are not necessarily rare. When a comic book has little market value, even if it is very old, there is little reason to pay for third-party professional grading and encapsulation. Comics which appear uncommon on the CGC census may be extremely common and of little value in the market. One common phrase often used with CGC graded comics is the phrase “highest graded”. According to the CGC census, the highest graded copy is rarely alone. The potential buyer for a highest graded copy should check to see if the copy is still the highest graded because more copies may be graded at any time. The buyer should also know if the highest graded copy is one of one, one of ten, or one of hundreds at the same grade. Over 25% of all CGC graded comics are also the “highest graded” for that issue. More than 1,000,000 CGC graded comics are technically the “highest graded” while fewer than 50,000 are the “single highest graded” copy with at least one lower graded copy on the CGC census. Everyone should be aware that the phrase “highest graded” rarely means “single highest graded”. Additionally, any premiums paid for the single highest graded copy of a comic book should be considered carefully, since another copy at the same grade or higher could potentially be graded tomorrow. There is also quite a bit of debate and mystery associated with the highest possible CGC grades of CGC 9.9 and CGC 10.  At the time of this writing, CGC had assigned the CGC 9.9 grade to 15,432 comics (about 1 out of every 270 comics graded) and assigned the CGC 10 grade to 3,503 comics (about 1 out of every 1,188 comics graded).  The CGC 9.9 and CGC 10 grades are overwhelmingly associated with recently-printed comic books.  80% of CGC 9.9 and 86% of CGC 10 books were printed since CGC opened to the public in 2000.  A high percentage of the remaining CGC 9.9 and CGC 10 comics were printed in the 1990s with chromium wraparound covers. It is common to point to the CGC 9.9 and CGC 10 grades (and their corresponding high prices in the market) as examples of extremes, even extreme absurdities, but it should be recognized that CGC 9.9 and CGC 10 are extremely infrequent, particularly for comics printed in the 1990s and earlier which do not feature chromium covers.  The oldest CGC 10 comic book is Kolynos Presents the White Guard #1 (1949), which was a promotional comic book for a toothpaste company. The oldest standard comic book graded CGC 10 is a copy of Thor #156 (1968). The oldest comic book graded CGC 9.9 is a copy of Zip Comics #7 (1940).  All three of the oldest CGC 9.9 and CGC 10 books listed above were graded by CGC more than 15 years ago.  For key issue comics, it is nearly universally-accepted that the three biggest superheroes in the comic book industry are Superman, Batman, and Spider-Man, so it is worth noting that CGC has graded 69 copies of Action Comics #1 (1st Superman, 1938), 68 copies of Detective Comics #27 (1st Batman, 1939), and 3,061 copies of Amazing Fantasy #15 (1st Spider-Man, 1962).  If there were unreported CGC resubmissions for copies of these (or any other) comic books, then the CGC census numbers are too high. While this means that the CGC census has errors, the actual number of CGC slabs in the market (and available for purchase) is always equal to the number reported or is even lower.  More information like this market report is available at slabdata.com, and more detailed CGC census analysis can be performed at cgcdata.com.

Why is this slab more valuable than that one?

This post is taken from the CGC Board where user “Hollywood1892” asked:

QUESTION: Why is NYX #3 More Valuable than New Mutants #87 and New Mutants #98?

ANSWER:

Supply and demand determine value” is easy to say, and it’s the right answer …but… I like putting actual numbers to those concepts. 

SUPPLY (CGC 9.8 universal counts):

New Mutants #87 = 1,454 

New Mutants #98 = 2,759

NYX #3 = 1,505

VALUE (CGC 9.8 universal sales average):

New Mutants #87 = $425

New Mutants #98 = $750

NYX #3 = $915

DEMAND (supply times value):

New Mutants #87 = 1,454 x $425 = $617,950

New Mutants #98 = 2,759 x $750 = $2,069,250

NYX #3 = 1,505 x $915 = $1,377,075

CONCLUSION:

NYX #3 is basically halfway between New Mutants #87 and New Mutants #98 in DEMAND (as defined above).  The individual prices for each copy are less important, because the supplies are different.  Put the two together (SUPPLY x VALUE) and you get something (DEMAND) that’s possible to compare across books.

There are plenty of objections to this simple calculation, such as:

What about the CGC 9.6, CGC 9.4, etc.?

What about all the additional raw copies that have never been sent to CGC?

What about the higher grades?

What about the fact that these books had different numbers of copies printed in the first place, regardless of how many are on the CGC Census?

What about more copies being sent to CGC all the time?

These objections are valid, but the original question reflected only one variable (Value) while the answer given here includes three variables (Value, Supply, Demand). It’s always possible to add more variables to any equation, but we quickly realize that both Pareto and Occam are more famous than we are for good reason…

They didn’t spend all day asking “But what about these 14 other things?”

Where is the cut-off for “High Grade”?

If we’re discussing where the cut-off for “high grade” comics would be, in terms of condition, then there’s an answer based on the eye appeal of a comic.  It’s hard to see how a comic book rated at least Very Fine to Near Mint (VF/NM, or 9.0 on the 10 scale) wouldn’t be a “high grade” comic according to its appearance.

However, if the comic was produced last week and was a 9.0 condition, it would actually be “low grade” relative to the quantities which would be available at 9.4 (Near Mint) and above.

It would be hard to say that 9.6 or higher is required for a comic to be “high grade” (regardless of age) since there are older comics which may not even exist in grades above 8.0, particularly comics from the beginning of the superhero genre of the late 1930s to 1940s.

Using the decades of the comics as a guide, and offering possible cut-off points as a percentage of CGC graded copies (Universal and Signature), the following chart provides some extra information to the discussion.

There isn’t a definite conclusion to be made from the numbers, and there isn’t a definite answer to when comics no longer “look high grade” from an appearance standpoint (being in the eye of the beholder), but more than 3,000,000 CGC graded comics were analyzed to produce the chart above. That’s at least a little more information than we had before.

Highest Graded! But is it Single Highest Graded?

There is a natural desire to celebrate owning (or offering for sale) the “Highest Graded” copy of a comic book, which can be determined by looking at the CGC Census.

There is also a difference between the “Single Highest Graded” copy of a comic book and owning one of the “Highest Graded” copies (are there 2 or 200?) graded (so far).

Here’s a breakdown of “Highest Graded” for Universal and Signature Series CGC graded comics, as of October 3, 2017 CGC Census:

172,631 different comic books on the CGC Census, 3,546,449 CGC graded comics, and 3,475,440 are Universal or Signature Series (about 71,000 are either Restored or Qualified grades).

There are 1,004,156 CGC graded comics which are technically “Highest Graded” – that is, 28.3% of ALL CGC graded comics, more than 1-in-4 CGC Graded comics are also “Highest Graded” copies.

There are 95,628 “Single Highest Graded” copies, and over half of them are also the “Only Graded Copy”… so 54,811 are single highest without any “competition”.

That leaves 40,817 “Single Highest Graded” copies which have at least one other lower graded copy on the CGC Census. That means 4% (about 1-in-25) of the 1,004,156 comics that can claim to be “Highest Graded” on the census are also “Single Highest Graded” with at least two copies graded.

Here is the breakdown of the 95,628 “Single Highest Graded” copies:

54,811 are “single highest” and “only graded copy”

13,101 are “single highest” and “one of two copies graded”

6,108 are “single highest” and “one of three copies graded”

3,668 are “single highest” and “one of four copies graded”

9,330 are “single highest” with 5 to 10 copies graded

4,165 are “single highest” with 11 to 20 copies graded

2,775 are “single highest” with 21 to 50 copies graded

797 are “single highest” with 51 to 100 copies graded

804 are “single highest” with 101 to 1,000 copies graded

69 are “single highest” with more than 1,000 copies graded

The “Single Highest Grade” in terms of highest total Universal and Signature Series copies graded are:

There are 256 different comics in the list, some duplicate CGC 10 so the total number of CGC 10 slabs 1949 to 1999 is 547.

Earlier labels noted the grade as CGC 10.0, but the current standard label states CGC 10.

The Age Old Question…

Some traditional names for the ages of comic books have been in place for a while (Golden Age, Silver Age), and some are still being argued (Copper Age, Modern Age).

This website will usually refer to comic books by the decade of their release (or date printed inside), rather than by ages, Golden, Silver, Bronze, etc.

While there is little doubt that a comic book from 1939 and another from 1952 are both Golden Age, there is a significant difference in comics from the 1930s compared to comics from the 1950s.  The addition of a sub-age in the Golden Age (like Atomic Age) may be useful for some, but in all cases these ages are linked with years.

For clarity and to eliminate confusion, this website will say 1950s comic books when it means 1950-1959, rather than attempt to separate Golden Age, Atomic Age, and Silver Age… which can all lay claim to at least a portion of the 1950s.

Comics from the 1930s, 1940s, 1950s, 1960s, 1970s, 1980s, 1990s, 2000s, 2010s, and 2020s will be referenced in the tags of articles and charts, when applicable.  Other age labels may be included, but will not be required.

Notes on CGC census information

The CGC Census is updated weekly at cgccomics.com and was updated periodically as early as 2003.  It is the policy of CGC to replace their census information with each update, so the author of this site created a database for prior CGC census data.  As each update was released, the database grew to the point that CGCdata.com was established to provide an easy method for searching current and historical CGC census information.  Permission was given by CGC for the compilation and provision of the historical CGC census data starting in 2003.  Earlier CGC census data files originally provided to the authors of the Standard Catalog of Comic Books from July 2001 and January 2002 were also provided to CGCdata.com.

Additional information is often requested which is not available in the CGC Census.  Examples include: grader notes, the identity of signatures, and individual submitter or dealer submission information.  That type of information is not available in the CGC Census, and is not available to CGCdata.com or slabdata.com.

The CGCdata.com and slabdata.com websites only contain information which was publicly available, which has been stored and compiled for analysis.

Case Study: Star Wars #1 (1977) CGC Submissions

A comparison of the number of CGC submissions for Star Wars #1 (1977) over time, including both the regular edition and the 35-cent variant.

The total submissions as of January 2017 are 5,895 copies of Star Wars #1 regular edition, and 195 copies of the Star Wars #1 35-cent variant.  The 35-cent variant is effectively a 1:30 variant of the regular edition (1 variant for every 30.2 regular), for copies of both submitted to CGC.

It is likely that the Star Wars #1 (1977) 35-cent variant is significantly lower than 3% of the existing/remaining supply, because lower grade copies of the Star Wars #1 regular edition are generally not “worth submitting” for professional grading when considering the resale value compared to the submission and grading fees.
