Why everything here is certified
Signatures are reproduced more often than most buyers realise, by outright forgery and also by machines and assistants signing on somebody’s behalf. Every item on this page has been examined by PSA/DNA, JSA, Beckett, SGC or CGC, and this index carries nothing else. That is a deliberate restriction, and the investigation that created the modern authentication industry is worth reading, along with what a certificate actually claims.
