This is a New England Patriots Flash Red Full Size Authentic Speed Helmet that has been hand signed by Mac Jones. The Flash helmets are delicate and may have some marks or scratches on them. This item has been witnessed and certified authentic by Beckett Authentication (BAS) and comes with their tamper-proof witness sticker. Beckett Authentication has recently changed their physical certificate card policy where they no longer match their tamper-proof sticker with a physical 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.
