How to spot a fake anime & pop culture autograph
Know the signer's usual placement
Many artists and voice actors sign in consistent spots — on the box window, a specific panel, or the base.
Boxes and windows matter
For Funko Pops, where and how the signature sits on the box affects both authenticity and value.
Convention signings are ideal
Items signed at observed events carry the strongest authentication — this is where witnessed certification shines.
Always confirm the certificate
Use the issuer's public COA lookup to verify before money changes hands.
