Services to Sellers

We offer the following services if you are seeking liquidation of your individual item, collection, accumulation, or entire estate. We can assist and advise you with the best method based on your particular needs.

Direct purchase

Immediate cash for your property – no commissions or delays.

We are aggressive buyers of U.S. and world coins including gold, platinum, silver and all others; gold and precious metal in all forms including bullion coins and bars, sterling silver; fine, estate and diamond jewelry, unwanted or damaged jewelry, wrist and pocket watches; U.S. and world paper money and tokens; U.S. and world stamps and postal history, all types of historical documents, autographs and artifacts including vintage Hollywood and sports related items; vintage postcards, photographs, paper ephemera and a wide variety of collectibles including military, Asian, Western and entertainment related.


Also known as private treaty sale, the seller consigns the property and we sell it on behalf of the consignor for a commission. This benefits the consignor as we are able to control the sale of the property and take the time necessary to achieve the top price for your property. Throughout our many years in the industry we have developed key relationships with collectors, dealers and investors worldwide who are eager to purchase quality material. The private treaty sale is especially effective with large, high quality or specialized collections. All consignments are insured by Lloyd’s of London while in our possession and until you receive payment.


For specialized property suited for auction, we can manage the entire auction process, including determining the appropriate venue or venues (both public and online).

Authentication and Grading

If necessary, we can handle all aspects of submitting coins and stamps for professional third party authentication and grading on our client’s behalf. We are official dealers for the leading recognized services including PCGS (Professional Coin Grading Service), NGC (Numismatic Guarantee Corporation), PSAG (Professional Stamp Authentication and Grading) and PSE (Professional Stamp Experts).
