I'm thinking of unloading some of my proof sets to bankroll other purchases (coins, of course). Before I do so though, is there anything special I should look for before listing? These are what I'm likely to put on the block:
Regular:
1992-S
1993-S
1994-S
1995-S
1995-S
Silver:
1992-S
1993-S
1994-S
1995-S
1995-S
And I also stumbled across a 1989 Mint Set, P and D.
Thanks.
