CGC Signature Series Grading — Whatnot Signature Purchase
Purchased an artist signature, sketch, or remark on our Whatnot stream? Lock it in with CGC Signature Series grading. We'll submit your book to CGC for professional grading and encapsulation under the coveted yellow Signature Series label — the gold standard for authenticated signatures.
Because the signing happens with us during or at the show, your signature qualifies for CGC's witnessed Signature Series program: CGC verifies the signature was authentically obtained, then grades, slabs, and seals the book with the yellow label that collectors recognize and value.
Add this service to your Whatnot win, and we handle everything from there — CGC submission, witnessing paperwork, tracking, and safe return straight to you.
Turnaround times depend on CGC's current schedule. Final grade is determined by CGC.
