He wore 9 for a short period when he returned after the suspension, was for a couple of months at the start of the season before the trade. Only a few have the 9 as the pic and these are the only ones with patches.
thats pretty cool that you have some of the few 9's produced then. I have a base Jordan card from the 90's - its nothing special, except that he is wearing #12 (the Jersey he wore when someone stole his #23 just before a game). I presume the only other card with #12 on it is in the legacy set.
