CGC Census – Submissions, Average Grades, and 76,832 Dots!

CGC has graded 76,832 issues at least ten times each for a total of 6,835,678 submissions, which represents more than 93% of all CGC submissions.

Collecting by Date – What is a Birthday Comic?

Most submitted book to CGC for each month in the 1970s…

Many comic collectors associate comic books with particular dates in their lives. In message boards and social media, users may post a photo of a “birthday comic” with a caption reading, “from the month I was born.” Using the CGC Census data, it is possible to identify the most often submitted comic book to CGC for each month and year for almost 90 years.

GPA Market Reports and the CGC Census

But turn those numbers into percentages and the surprises abound. Take a look at the most recent twelve months in terms of what’s trading more often than you might expect.

Newsstand Books – The Way It Was

Before the introduction of the direct market in the late-1970s, every comic book was a “newsstand” edition. Comics published from the 1930s to the late-1970s were all newsstand editions, which meant three things: 1) They could be returned for credit if they didn’t sell by a certain date, 2) They were not ordered according to demand, but according to distributor processes, and 3) both serious and casual comic collectors obtained copies of identical comic books, since all books were newsstand editions.

With the introduction of the direct market, comic book publishers were able to supply comic shops with exactly the number of copies of each book that the retailer purchased. Additionally, in exchange for a discount on the price of each comic book, the direct edition books could not be returned for credit. Comic shop owners could decide which books would sell best, which books would be good to keep in the back issue inventory, and which books they didn’t want to purchase at all.

CGC Math – Paint Me A Picture

Every comic book is high grade, mid grade, or low grade – even if collectors have different personal definitions for those categories.  Picture this:  Using the CGC Census, it is possible to visualize what has been CGC graded so far, and perhaps discover clues about what grades remain to be CGC graded (or not!) in the future.

CGC Census Totals – 20+ Years Set The Pace

The CGC Census has been reported throughout the 21+ year history of CGC grading, beginning January 1, 2000. Using end-of-year CGC Census totals from, the history of CGC can be summarized as:

History of totals on the CGC Census

Having this many points of data allows for a calculation that “predicts” the CGC Census numbers based upon the amount of time which has passed since CGC began grading.

That formula result is a little “ugly” to look at, but it works very well for the first 21+ years of CGC’s history.

Y = 0.00000000505*X^4-0.0000585*X^3+0.250095*X^2+5.88495*X

Where X is the number of days since January 1, 2000.

If the formula continues to be similarly accurate, the following numbers would be expected for the end of 2021 through 2025.

This is a significant increase predicted, nearly doubling the 21.5 year CGC Census totals of January 2000 to July 2021 in the time span of just 4.5 years from July 2021 to December 2025. However, the CGC Census did double most recently in just 5.5 years from December 2016 to July 2021.

Slabbing Comics – CGC Census Retrospective – Decades of Popular Submissions

Slabbing Comics – CGC Census Retrospective – Five Years at a Time

This month’s article steps through time in five-year blocks, looking at the CGC Census for books graded during 2000-2005, 2006-2010, 2011-2015, and 2016-2020. The Top 25 for each of the five-year timeframes do have many of the same books, however, these are separate lists isolating the books graded by CGC during those five-year spans and not a running total since CGC began. The Top 25 for the whole timespan from 2000-2020 is presented at the end of this article.

Starting with the Top 25 CGC Submissions for 2000-2005, the results for the first five years (technically a little over six years, from late 1999 until the end of 2005) have Wolverine Limited Series #1 as the most submitted book to CGC in the timeframe.

Most submitted books to CGC between 2000 and 2005.

Slabbing Comics – CGC Census Retrospective – The First Two Years

The first CGC graded comic book was Walt Disney Comics & Stories #1 (Dell Publishing, 1940) – CGC Serial #0000001001 (Invoice 0000001, Item 001), originally graded November 9, 1999.  CGC opened to the public on January 1, 2000, bringing the “slab” concept from coins and cards to the comic book market. 

Take a closer look at CGC’s first 100,000 graded comics.

The first comic books submitted to CGC provide a “snapshot” of the state of the comic book market and CGC as it was during 2001.  The market seems to have moved on from the “hot new books of the day” from 2001, but CGC is still spending lots of time grading “hot new books of the day” in 2021.  Does our past show us our likely future?

2020 Year End – Top 25 CGCAMC Calulation

The third article on the topic of CGC Average Market Capitalization (CGCAMC). 

The CGC comic book market was significantly impacted by the events of 2020, so much so that the final 2020 list for the Top 25 comic books by CGCAMC calculation is nearly 25% higher than the mid-2020 list.  For the first time, Action Comics #1 and Detective Comics #27 are not in the Top 3, replaced by more recent key issues with higher CGC populations.  Is this a reflection of a price bubble or a reflection of the books valued more by the market?

CGC Average Market Capitalization (CGCAMC): An Introduction

When the headlines say, “COMIC BOOK SELLS FOR OVER $3,000,000!” it is certainly an attention-grabber.  It is not hard to name the most valuable comic books of all.  Do those highest priced comic books truly represent the most total market value for an issue?  Would it be better to have 2 copies of a comic worth $100,000 each or 50 copies of a comic worth $5,000 apiece?
