JSA SIGNATURE AUTHENTICATION

Already signed? Get it authenticated & graded

If you already own a signed comic or collectible, we verify the signature through JSA, then clean, press, CGC-grade and encapsulate it with the famous gold Signature Series label.

How it works

1

Send your signed item

Your already-signed comic or collectible comes to us.

2

JSA authentication

The signature is verified by JSA, the trusted authority.

3

Cleaned, pressed & graded

We maximise the grade and submit to CGC.

4

Gold label & returned

Encapsulated with the CGC Signature Series gold label and posted back.

BEST VALUE

Our full service — clean, press & grade

Pressing a book before grading gives it the best possible chance at a higher grade — and our full service bundles cleaning, pressing and CGC grading into one submission for less than buying them separately.

  • ✓ Maximises the grade before it’s sealed
  • ✓ Cheaper than cleaning & pressing then grading separately
  • ✓ 20% off cleaning & pressing when bundled
  • ✓ £5 postage discount on full-service items submitted together
