About Us


We have been in business since 1981. The combined resources of our staff represents over a century of numismatic business experience.

Member of Professional Organizations:

The principals of our firm are members in good standing of the American Numismatic Association. This is the closest thing to a regulatory body in this business. Chartered by Congress in 1898, the members abide by a published code of ethics. This affiliation will also serve as an arena for any arbitration or mediation, (if the need should arise), due to any complications in a given transaction.



Dealer as Teacher:

We try to instill in our clients a sense of knowledge regarding the field of numismatics. Remember that a little knowledge can be dangerous. Accordingly we will try to impart an understanding of the dynamics of good, sound acquisition and disposition methods.


We at SDL, are direct purchasers of all American coins and stand ready to purchase any size collection. Please offer us any coins which you may want to sell. We will offer you the highest possible prices that we can pay. If you prefer, we also accept consignments on a commission basis and will provide a free evaluation of your position on request.
