This Autographed Blue Jersey has been Personally Signed by Stefon DIggs of the Buffalo Bills. This item is 100% Authentic to include a hologram by Beckett Authentication Services. This item may 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 multiple autograph signings with Stefon DIggs and we have several of these available. You may receive a signature on the #1 or #4. The one you will receive will be of similar quality to the one pictured. This item can be verified through BAS. This is a X-Large sized, non-branded, custom-stitched Jersey.
