This is an Official MLB Baseball that has been hand signed by Dick Hall. This item was inscribed "66 World Series Champs." There is an imperfection in the signature as shown. 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.
