I have collected 1 card of each different game used material that has been featured on a Cal Ripken Jr. card. The materials are: Jersey, Pants, Bat, Baseball, Fielding Glove, Batting Glove, Stadium Seat, Dugout Bench, Base, Hat, Helmet, On Deck Circle, Infield Dirt, Jacket, and Outfield Wall (newly discovered). I couldn't believe all the different materials they put on cards. The helmet was by far the hardest to track down. They only made it in 2006 Topps Sterling for Ripken.
NOTE: I did not include items such as jersey buttons, patches, tags, bat barrel pieces, etc. I consider those to be just specific parts of the overall jersey or bat or whatever material it is.
Hat (the first "1" is the hat piece):
Helmet (the "1" is the helmet piece):
On Deck Circle:
