Alex Rodriguez Arod Batting Helmet Signed Autograph Auto Autographed MLB Baseball PSA PSA/DNA COA Seattle Mariners Diamond Collection Authentic. This listing is for a Alex Rodriguez Arod Batting Helmet Signed Autograph Auto Autographed MLB Baseball PSA PSA/DNA COA Diamond Collection Authentic. The hand signed autograph has been authenticated by PSA. The item comes with the serial numbered certificate of authenticity (COA). This serial number can be looked up on the PSA website where the item will be described. The PSA/DNA authentification sticker with the serial number matching the COA is attached to the item. This authenticates the autograph such that the hand signed autograph is guaranteed to be authentic. PSA is one of the most respected autograph authenticators in the hobby. The market respects their opinion. The autograph looks great. The item is shown in the pictures. This is a cool item. It would look great on display in a man cave or sports bar! It is a must have for the true fan. PLEASE NOTE that this is an old item and the inside padding has become detached from the helmet. It could likely be reattached with double-sided tape or something. It stays in place. I leave it to the buyer to decide the way they would prefer to address this. There is some powdery debris that has come off as well from the foam which can be cleaned.
