DO YOU HAVE DUPLICATES? I help museums & archives to sell duplicate coins, stamps, old envelopes, currency, autographs, and collateral items. I work as an agent to place items in international auctions. I can provide a sorter's guide and guidelines for selling these items at auction. Doug Mattox Mattox Coins & Stamps P.O.
