1985 Topps is a 792 card set.Cards 389-404 feature selected members of the 1984 U.S. Olympic Baseball Team. Of course, the USA subset contains the only true Rookie Card of Mark McGwire; however, not all members of the 1984 Olympic Team were allowed to appear in '85 Topps. Will Clark and Barry Larkin were prohibited from appearing in the set, as they still had NCAA eligibility and in 1985, their appearance would have been a violation of NCAA rules.
