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.
