Topps has been making baseball cards since 1952, the collector's market is willing to pay top dollar for some of them.

The Topps 1968 Nolan Ryan rookie card is a notoriously ... print run because in 1954 Williams was exclusive to Topps for baseball cards (he has the first and last card in the 1954 Topps set).

The decade's first iconic card is neither a rookie card nor a Hall of Famer. However, it does come awfully close on both those fronts. It's the second-year card of Yankee captain Thurman Munson.
