From looking at both Beckett and comc.com, they appear to have different listings.
From Beckett, it appears to be 2014 Panini Playbook Jerseys, which in both their online listings, and the published book that came out recently is still listed with numbers. In those checklists, the card is listed as #9 with a SN25. I would believe that is what it is. There is currently no Jerseys checklist on this site and all I have is the numbers, and can't come close to listing all the letters as card numbers.
On comc.com, it appears that it would probably be listed under "2014 Panini Playbook Booklets Right Side Picture Silver".
Good luck, and I'm jealous of the card!
