The provenance and authenticity of the items offered by SCP Auctions have been researched extensively. Where appropriate, we have employed the services of the foremost independent authentication firms such as PSA or SGC for card grading and authentication services; PSA/DNA (Professional Sports Authenticator), and JSA (James Spence Authentication) for autograph authentication, and MEARS (Memorabilia Evaluation and Research Services) and PSA/DNA for game used equipment. LOA’s (Letters of Authenticity) from third party authenticators, as well as those from relevant sources, are indicated in the lot or item description at for any auction or direct sale items.

Please call SCP Auctions for any further description or information regarding authentication on any auction lot or private sale item.
