This is an Official M.L.B Baseball that has been hand signed by Hideki Matsui. Matsui autographed this baseball in both English & Japanese. 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 serial numbered hologram with a physical certificate. A certificate can be printed on Beckett's website for the matching authentication number.
