Here is what I do know, there is no number on the card, it was just something ITG did not do. Now, most of the time there was a checklist from ITG on their website, but for these cards most of the time it was an alphabetical list from Beckett and they numbered the cards 1-X. So how are you to know, you don't. There are similar issues with team cards and what not as well, sometimes they used the player number but most times it was alhpa and assigned a generated number. Show cards like this are notoriously bad, you have to search so many different terms just to find them.

BTW, Beckett is not the best at getting checklists right. Matter of fact I was on today looking for a card, clearly numbered on the back RR53. Beckett had it listed as R53, but the description had it only as WIN as the difference. I have seen that on MANY sets. So go by year, make and player. Good luck, sometimes it can take a while.....
