Dang it they are 2012s the year before Panini started labeling the backs with what set the cards were coming from. They don't seem to be listed in the database. The best I can tell they were part of a 10 card set (sold wrapped in a clear pack as a set). 2012 Panini Super Bowl XLVI Peyton Manning Career Highlights?
I found this link which mentions the 10 card Colts set along with a 9 card Giants set (which is in the database). They are listed as "NFL Experience" https://www.sportscollectorsdaily.com/panini-offering-special-nfl-experience-card-sets/
I collect: Baseball, Football, Hockey, Mostly Vintage pre1980, My Homie teams - Washington/Baltimore Teams Senators (Twins, Rangers), Expos/Nationals, Redskins, Capitals, Bullets/Wizards - HOFers - Non-sport (mostly TV shows and movies).
My Trade List is very much a work in progress
