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.

Percent vs. Percentage

The terms ‘percent’ and ‘percentage’ are used interchangeably on this website. While ‘percentage’ might be a better word to use in some circumstances, it is always a longer word to use, and therefore clutters some posts or chart titles which are already long enough.

What is slabdata.com?

Slabdata.com is a blog established in 2017, associated with CGCdata.com Census Analysis. The CGC census data available is from July 2001 to present. No information is available at CGCdata.com that was not publicly available on the official CGC Census at cgccomics.com. The data has been compiled with the permission of Comics Guaranty LLC since 2003, and the search engine for CGC Census Analysis has been available at CGCdata.com since 2011. Greg Holland is the administrator of CGCdata.com and slabdata.com.

… but what is a slab?

‘slab’ is the common term used to refer to professionally graded comic books. The term ‘raw’ is often used to refer to any comic book which has not been professionally graded, in other words,’raw’ is the original way a comic book is published and distributed for reading and collecting.

In addition to receiving a third-party opinion on the condition of the comic book (including a check for restoration), slabbed comics are encapsulated and assigned a serial number by the grading company.

As of January 2017, only the CGC grading company has made their census data public. When another grading company provides census data, it will be incorporated with their permission into the database and referenced on this blog.
