I have a bunch of Pacific cards with the Super Bowl XXXV stamp, as I went to the NFL Experience at the Super Bowl that year where they were doing the stamping. However I only got NFL cards stamped, as did the majority of other people there. I would think the Super Bowl stamps on baseball cards would be extremely rare. Nice to see you add some more rare pieces to your collection.
Collecting John Stockton, Karl Malone, Ivan Rodriguez, Gary Carter & UF player rookie year cards. Plus Jedd Gyorko rookie and prospect cards.
