Consignment to CNG Auctions

Our first auction was held on May 1, 1987. We have conducted more than 115 printed auctions since then, and in the process have built the world's most comprehensive mailing list (over 40,000 names) for collectors of ancient, medieval, world and British coins. In addition, we have conducted over 490 electronic auctions. More than 10,000 clients are registered to bid in our electronic auctions. Because we run both electronic and printed sales, we are equipped to handle a broad range of value.

CNG holds three major printed auctions each year. Our "Triton" public auction is held in New York in January, in conjunction with the New York International Numismatic Convention. Our two mail bid sales, which close electronically, take place in May and September. For each printed auction, with an average of 1500-2000 lots, we produce a fully illustrated catalogue, which is a valuable reference tool as well as an opportunity to buy. Please refer to "News and Events" on this site for a complete list of future printed auction dates and consignment deadlines.

On this web site we hold continuous electronic auctions offering a broad range of material. Each sale lasts for two weeks and closes on a Wednesday. Through these electronic auctions we offer over 15,000 lots of ancient, medieval, world and British each year.

We will be glad to discuss your possible consignment to public auction, mail bid sale, or electronic auction.

Direct Selling to CNG

We are constantly searching for coins to buy and would be pleased to hear from anyone, collector or dealer, who has ancient, medieval, world or British coins to sell.

If you are not sure whether it is better to sell through auction or for immediate cash, we can discuss the options with you and help you to arrange the most advantageous sale method to suit your circumstances.

We may be contacted by email, fax, phone or mail.
