AUCTION COMMISSION BIDDING: Can't make it to the sale you want to bid in? Afraid that you will overpay for something or (worse) underbid and lose the coin you want? Never fear—we are at your service for most major coin auctions (in our field) in the U.S. throughout the year. For a standard 5% fee we will inspect the lots you want to bid on, advise your bidding strategy, and execute your bids safely and anonymously. Not only will you benefit from our experience and presence, you will also eliminate us and our other clients from your competition!

AUTHENTICATION AND CERTIFICATION: Our verbal opinion is always free (as should be everyone's), so long as there is no out-of-pocket expense (i.e., please provide return postage if you send your coin to us). If you require a certificate or any other documentation (e.g., a court affidavit), however, the fee is $50 per one-page item plus return postage. (restrictions apply)

APPRAISALS, CATALOGING, AND/OR CONSULTING: These services are available for a fee of $150 per hour or $1500 per day, plus expenses (if away from our office).

CONSERVATION: We are proud to offer professional coin and artifact conservation, particularly for coins recovered from shipwrecks. Rates are hourly, as above ($150 per hour). Our method is proprietary and proven, but not all pieces are ideal for our service, so please understand that we cannot be responsible for the results, which may not always be reversible.
