I don't really have any cards that would be considered "rare"I guess my e98 Mathewson and Young would be the "rarest" I own. I've already posted pics of the Mathewson so many times, so i'll show the Young. t206museum didn't have a t206 polar bear back with parts of 4 backs.. so maybe, just maybe its rare probably one of the nicer PSA 1 Youngs. Just has a light wrinkle and a spec of paperloss, but I think it still looks nice
