West End based coin dealer, Stephen Fenton, had always been interested in auctioneering and in 2004 he decided to bite the bullet and hold his first auction under the banner St James’s Auctions. Having had a long association with Stephen, Baldwin’s were the obvious partner choice and since conception the auctions have grown from strength to strength. Together our two companies have worked hard to build the brand of St James’s Auctions.

Just four years after the first sale St James’s were the very proud auctioneers of four exceptional Russian coins that took the numismatic world by storm. Among them was an Elizabeth gold 20-Roubles, an amazingly rare coin in type and condition, which sold for an incredible £1.55 million, setting a new world record for the sale of a non-American coin. In 2014, after 10 years in partnership, Stephen Fenton decided to run the St James’s brand by himself and enlarge his own auction team. To date the auctions are still being held at The Cavendish Hotel in London.

New York

Formed in 1998 the New York Sale partnership comprises three of the most prestigious numismatic auction houses in the world, who together form a powerful international force in the numismatic industry. Original partners A.H. Baldwin & Sons Ltd (London, UK) and M & M Numismatics Ltd. (Washington DC and Basel, Switzerland) were subsequently joined by Dmitry Markov Coins & Medals of New York (USA) in 2000 and have expanded to hold two multi-million dollar sales per year, specializing in Ancient and World coins and Russian Coins and Medals.

Held each year in conjunction with the largest and most important annual numismatic event (The New York International Coin Convention) the group holds two auctions during the week long event. By combining a vast array of experience and knowledge the group strives to offer the best possible service to their clients and customers, whether buying at the auction or a potential vendor for the sale, any one of the partners have a full complement of specialists available to offer advice. Catalogues are produced to the highest possible standard and may be used as a useful reference for serious buyers and coin collectors.

Over the years the partnership has aimed to achieve the best possible prices for their vendors and undertake a full advertising and marketing strategy which is proven in the excellent results achieved year upon year. In 2004 the sale of an 1825 Russian silver Rouble for US$603,750 broke the world record price achieved for any non-US coin sold by public auction and since then lots have regularly attained prices well above estimate.

Hong Kong

Baldwin’s had a part in the establishment of the first Singapore Coin Auction in 1986, and consigned frequently over the years. We were therefore well placed to take over from Spink when they withdrew from the original partnership in 1993. We went on to set up the Taisei, Baldwin, Gillio enterprise and later (in 1999) the Baldwin — Ma Tak Wo partnership. The Hong Kong Coin Auctions are numbered from this series and deal almost exclusively with Asian numismatic material.

Ma Tak Wo has been a major player on the Asian numismatic scene for over 3 decades, first as an avid collector of Chinese (including Hong Kong and Macau) coins and paper money and then as one of the principals of the Taisei group of companies which organized the highly successful Hong Kong and Singapore coin shows and auctions. He is a well established writer of numismatic material and has produced 8 numismatic titles which have become standard references in their respective fields

The group has grown to hold two successful numismatic auctions a year in Hong Kong in conjunction with the group run bi-annual Hong Kong International Coin Convention & Antique Watch Fair. Dedicated to providing professional and conscientious services to collectors, dealers and vendors alike the partnership has grown to become a leading light of Asian numismatic auctions. Amongst its achievements the Hong Kong Coins Auction can boast selling “one of the rarest coins in the world”, The Chang Tso Lin (1875-1928) Pattern Gold $50 for US$575,000 (including buyer’s premium) and in 2009 a Ming Dynasty 1-Kuan note sold for a record breaking US$19,000.


Arabian Coins & Medals LLC of Dubai, UAE, is a company set up by André de Clermont and Edward Baldwin, independent of Baldwin's, in 1998, to create a foothold in the Gulf coin market, and particularly the market for Islamic coins. The plan was to hold auctions and develop a local retail market. An office was acquired in central Dubai. The first auction, held jointly with Baldwin’s Auctions Ltd under the brand name Emirates Coin Auction, took place in Dubai in March 1999. The ground-breaking catalogue was bilingual, with English and Arabic parallel text, and was in Arabic format, paged from right to left.

In March 2000 the second Emirates Coin Auction took place. This was a two day event held at the Dubai Chamber of Commerce and Industry. In addition to the usual coins and banknotes, a selection of Islamic antiques was offered.

In 2001, the decision was taken in conjunction with Baldwin’s, to move the auction venue to London for logistical reasons, while retaining the office in Dubai. Since then 27 auctions of mainly Islamic coins have been held, under the brand Islamic Coin Auction.

ACM is justly proud of its long presence in the specialised world of Islamic coins, and of its well established base in the United Arab Emirates.
