I am looking for a sports authenticator that uses the certificate sequence COA12345 on the holograms

I am looking for a sports authenticator that uses the number sequence COA12345 on their holograms on authenticated items. I have an autographed football that has been authenticated, but I misplaced the paper certificate, and don't remember who it was authenticated by, the only thing on the ball is a hologram sticker that has COA and 5 numbers following (COA######). I am trying to find which authenticator uses this sequence on their items so that I can get a replacement certificate.

Thank you.
