CGC does grade magazine-size books. However, CGC does not grade treasury-size books as their size exceeds even the largest available CGC holder.

Yes, under the following circumstances: CGC's prestigious Signature Series label (yellow) is applied to comic books that have been signed under the direct observation of a CGC employee or a select CGC authorized witness, or in select instances where CGC accepted signed books directly from the signer / publisher. The signatures are authenticated by CGC, and the labels indicate who signed the book, the date it was signed and, in some cases, the location where it was signed. If a book is signed without a CGC representative present, it can be verified by James Spence Authentication (JSA) and received a CGC/JSA yellow label. Signatures that are not verified receive a Qualified label (green), and will receive a Qualified grade. To learn more about CGC Signature Series, visit https://www.cgccomics.com/signature-series/.

In order to certify a polybagged book CGC will remove it from the polybag and submitting it assumes a customer’s permission to do so. Customers do not need to remove the polybag before submitting.
