APMD dealers have all passed a strict background check, are held accountable by the PNG & APMD Code of Ethics, have achieved a reputation for excellence in the precious metals industry and are legally bound to settle disputes.  The APMD program was developed to provide an even higher level of confidence for precious metals buyers by maintaining the same rigid standards of excellence for PNG precious metals dealers—and more.



Our in-house appraisals are most often free of charge.  If however you need an appraisal typed on our letterhead usually for estate purposes or to be presented in court, then the charge is $75 per hour with a minimum charge of $75.  The appraisal process is simple.  Once you bring your coins to us we will sit with you and itemize the value of your collection.  If you decide to sell to us then we will pay you the appraised price, if you choose to keep your coins then there is no charge except in the instance noted above.

Rare Coin and Bullion Sales

Whether you are looking for a $19 Indian cent or a $500,000 rare coin, the professional numismatists at RCNH can help you.  We have a vast inventory and would be happy to send you a scan of anything in our inventory or with proper references send a coin to you for approval.  RCNH provides precious metals at a very modest transaction cost.

Want Lists

Many dealers offer want list services but don’t actually service them beyond one or two coin shows.  At RCNH we don’t give lip service, we actually keep your want list active until you tell us your needs have changed.  A word of caution!  Do not give us your want list if you are in a hurry to complete a set or series of coins.  Any true professional numismatist will tell you that truly honestly graded coins are hard to find.  That is why we advocate to buy the coin and not the holder.  If you are looking to plug holes in your series of collecting interest then we are not the dealer for you but if want coins that you will be proud to own then please call us.  We will only sell coins that we want to buy back at a future date.  

Auction Representation

One of the most popular services that we offer.  Whether you are purchasing or liquidating you can benefit from our many years of experience.  

If you decide that now is the time to sell your coins, you will need advice as to which auction or auction house may best serve your needs.  We have dealt with every major auction firm in the U.S. and have significant negotiating clout to maximize what you can realize for your coins; often you will receive more by consigning through RCNH than on your own.

If there is a particular coin coming up for auction that you need a professional opinion on or need to be represented in a confidential manner, RCNH can provide this service for you often at a nominal charge.  You will receive the benefit of our years of experience to render an opinion that you can be assured you will be comfortable with.

Submission Services

Since we are members of all major grading services including the newly formed CAC service we can submit your coins for grading at any point.  Once we receive your coins we will call and give an opinion as to which service and grading tier would be best to send your coins.  You will be charged only our cost plus additional shipping and handling charges.

Upgrade Program

As far as we know we are the only firm in the country that offers this service to anyone that calls us.  Since third party grading is not perfect there are situations in which a coin may be resubmitted or sent to a competing service for regrading.  We can look at your coins and determine which coins would be good candidates for this service so that you can maximize your coins value.  Please call today so that you can discuss this option with one of our numismatists.

Expert Witness Services

Because of our knowledge and experience, at times we will testify for various law enforcement agencies.  If you should need an expert to testify for you, one of our numismatists will be happy to discuss your particular situation with you in confidence.

eBay Service

If you are technologically challenged or just don’t have the time and wish to sell your coins through eBay then we can help.  Many clients opt to liquidate their coins in this manner and we will be happy to give our opinion as to whether your coins would benefit from this option.  We routinely sell coins through eBay and have the latest photography equipment to put your coin in the best positive light.  We also have the experience to correctly describe your coin and put it in the best possible light as to generate a great amount of interest among potential bidders.  We charge a nominal fee for this service but this is often a good choice for coins that may not make the cut for a mainstream auction house.

Our Staff

David Carleton, President

David Carleton, President and numismatist at RCNH started collecting coins when introduced to the hobby by his father and grandfather in the 1950's.  After a lull he began buying Krugerrands in 1976 and sold at the height of the market in 1980, this sparked a six year collecting binge that culminated in David meeting Warren, his future business partner and mentor.  After working together for several years both left the firm they were working with and started RCNH in 1990. 

Warren Mills, Vice President

Lou Roten

Like many involved with coins, Lou became interested in coins at a very young age, influenced by his grandfather. Though his grand-dad was not a collector, he loved American and European history, creating an interest in historical artifacts which included coins of the world. Six years study of Latin and two of ancient Greek in high school, reading Caesar, Cicero, Virgil and Xenophon, led to an interest in ancient coins. Sadly, his entire collection was stolen while still in his teens, though his stamp collection was untouched. College, graduate school, then work took over for many years, traveling to and working in 44 countries for more than 30 years. More recently he taught mathematics and physical sciences at a local university for last ten years. All the while the interest in coins continued until the opportunity came about in early 2014 to revisit this great hobby/avocation and to join RCNH for total immersion in the business, learning from the collective experience of the exceptional professional numismatists at RCNH. Coin interests are early 19th century silver and copper, especially varieties, often a result of expedience and reuse of dies.

Donald Severance, Currency Consultant

Don has been a professional numismatist for over twenty-five (25) years.  His interest began originally collecting coins, but then was soon introduced to paper money.  Although versed in both, Don’s passion was with paper money.  Intrigued by the history, beauty and detail of each piece he researched and assembled an impressive collection of U.S. currency.  He eventually formed his own company, buying and selling every type of currency, attending shows across the country and building a client base that trusted and relied on him to find that perfect piece.

In 2000, Don became a contributor to the Standard Guide To Small-Size U.S. Paper Money.  Shortly thereafter, Don joined Spectrum Currency as their East Coast Representative.  While at Spectrum he traveled the country buying and selling currency and acquiring collections for auction.  Don has made many currency discoveries in his career including a new Friedberg catalog number that was chronicled in the Bank Note Reporter.  A note that was previously not known to exist.

Don eventually left Spectrum to continue his career working for himself and to focus on his expansive clientele.  Don works very closely with Rare Coins of New Hampshire as a Currency Consultant and together we have bought and sold over 7 figures in currency.  How can we help you?

Don is a member of the PCDA (Professional Currency Dealers Association), ANA (American Numismatic Association) and FUN (Florida United Numismatist).
