This is a Rawlings Big Stick Bat that has been hand signed by Ken Griffey Jr. This item was inscribed "HOF 16." This item has been certified authentic by Beckett Authentication (BAS) and comes with their tamper-proof sticker. Beckett Authentication has recently changed their physical certificate card policy where they no longer match their tamper-proof sticker with a physical certificate. If the item features a Beckett Authenticated QR Code, the item does NOT come with a matching certificate. The tamper-proof sticker holds the value in the authentication process while the certificate does not. A certificate can be printed on Beckett's website for the matching authentication number.
