… 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.
