A friend of mine has a couple of early 1990s trading card sets. Both are in their original boxes and, as far as I know, are complete. One still has the original plastic wrap on it; the other does not.
Set #1 is 1991 Topps baseball, a set of 792 cards. Set #2 is 1990 Score, a set of 704 cards + 56 'Magic Motion' cards. I'm looking for an approximate value for each. My first thought was $10-$15, max. Was that correct?
