This is a White Majestic Atlanta Braves Authentic Cool Base Jersey that has been hand signed by Ronald Acuna Jr. This jersey is Size 52. 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.
