I've searched the web but have been unable to find the original U.S. Mint issue prices for some Modern Commemoratives. Specifically, for the various 1983/1984 Olympic gold & silver, uncirculated & proof, sets. Also, for the various 1987 Constitution gold & silver, uncirculated & proof, sets.
Surely, the U.S. Mint MUST have this info available somewhere on the web? Any help or suggestions would sure be appreciated Thank you.
