This Autographed Alternate Eclipse Riddell Full Size Speed Rep Helmet with the inscription of "Fins Up!" has been Personally Signed by Mike Gesicki of the Miami Dolphins. This item is 100% Authentic to include a hologram by Beckett Authentication Services. This item will come with the new Beckett Authentication hologram that has a scannable QR code rather than the traditional COA. If you would like to have a COA, you are welcome to reach out to Beckett for a printed certification once you receive your item. This is a BAS Witnessed Protection Program item which means a Beckett Authentication Service representative was present when this item was being signed. This is a stock item. We conducted an autograph signing with Mike Gesicki and we have several of these available. The one you will receive will be of equal quality to the one pictured. This item can be verified through BAS Witnessed.
