Already signed? Get it authenticated & graded
If you already own a signed comic, magazine or card, we verify the signature through JSA, then clean, press, CGC-grade and encapsulate it with the famous gold Signature Series label.
How it works
Send your signed item
Your already-signed comic or collectible comes to us.
JSA authentication
The signature is verified by JSA, the trusted authority.
Cleaned, pressed & graded
We maximise the grade and submit to CGC.
Gold label & returned
Encapsulated with the CGC Signature Series gold label and posted back.
With or without cleaning & pressing
JSA authentication is our one service where cleaning & pressing is optional. Pressing before grading gives your book the best possible chance at a higher grade, so most collectors choose it — but if you’d rather we grade your item exactly as it is, choose grading only.
- ✓ Clean, press & grade — maximises the grade before it’s sealed
- ✓ Grading only — your item graded exactly as it comes
- ✓ Either way, JSA authentication is +£32 per signature
