1991 Pacific is loaded with variations. Many are well-known. However, one major variation that remains undocumented affects one of the set’s biggest stars: Barry Sanders. His card, usually #144 in the set, can also be found missing the 44 on back, making him #1 in the set. A couple of knowledgeable collectors have mentioned that the #1 variety was issued in a package that included a pin of Barry. Very unusual, and a cool addition to any E&V collection!

this is actually pretty common…

they just happened to renumber them…
its possible that they did the same sort of renumbering in other sports, but not by Pacific… there are several other NFL guys that were renumbered, i believe…
this is similar to the score 100 hottest from around the same time… which is actually a little bit harder (but still not terribly difficult) to track down.
Thanks for the link. Aside from how scarce or common they are, it makes a pretty cool, unlisted variation for a 1991 Pacific master set. Do you know of any others players from the PIN issue that have different numbers than their wax counterparts?
#549 Stacy Danley variation. I have one in which the text on back is across the black borderline on the back of the card.
