The same can be said for the 1985 Topps Mark McGwire USA. Lots of debate over XRC versus RC. Most people today now consider his 1987 Topps his Rookie Card and his 1985 Topps a "prospect" or extended rookie card.
FWIW, I consider 1987 the McGwire rookie card because it's his first topps MLB uniform appearance. While I like and collect Team USA, I don't consider any USA baseball card of a player as their rookie card.
