The base jersey is a simple retail authentic from 2001, featuring the popular Reebok "Helmet Tag" jock tag. However, the jersey numbers are not retail - they are the authentic on-field heavyweight print numbers featured on Bills game-used jerseys in 2001. The retail numbers on RBK jerseys were much thinner. Jim became the first player in Buffalo Bills history to be honored with the retirement of his jersey number in November of 2001.
My best guess is that this jersey was made in-house by the Buffalo Bills equipment staff for Jim's retirement ceremony. I found a style match of this jersey from a Kelly family member present at the ceremony, but I cannot confirm if it is the exact same jersey.
This jersey is in excellent condition & is frankly the highest-quality version of the classic 90's jersey design style you'll ever see! See pics for details and closeups!
