Felix Hernandez Autographed Official MLB Baseball Seattle Mariners "P.G. 8-15-12" Beckett BAS Witness

This piece is BAS Witness Authenticated — the highest authentication tier offered by Beckett Authentication Services. A Beckett representative was physically present at the signing, observed the autograph being applied, and applied the tamper-evident hologram on-site. The witnessed designation provides the strongest possible chain-of-custody evidence in the industry, and Beckett maintains a public lookup tool so you can confirm the piece independently in under a minute.

1. Locate the BAS Witness hologram applied to the item at the signing event. The serial number is printed on the hologram itself.
2. Visit Beckett's verification page at beckett-authentication.com/search.
3. Enter the serial number into Beckett's lookup tool.
4. Confirm the match. The lookup will return the item details and confirm the Witnessed authentication — these should match the piece in your hands.
