CGC Private Signings

How do CGC Private Signings work?

By streamlining the Signature Series program through Private Signing events, CGC makes it easier for collectors all over the world to add signatures to their books and reach their collecting goals.

CGC facilitates Private Signings at conventions. Customers bring their books to the CGC booth before the cut-off time, fill out a submission form, and pay fees by credit card. CGC then gets the books signed, grades and encapsulates them with a Signature Series label, and ships them back to the customer.
