PSA/DNA, one of the leading third-party autograph authentication services, announced the hiring of two new full-time authenticators on September 30.

Grad, who was PSA/DNA’s principal autograph authenticator, joined PSA/DNA in 2002 and since 2013 has also been the autograph authenticator for the History Channel’s hit show, Pawn Stars. Sobrero was a PSA/DNA full-time authenticator for about six years.
