Based in Geneva, Switzerland, ADM, started in 1972 the first coin shop in Geneva. He is recognised as a numismatic “pioneer” for his contribution in the creation of early associations and collectors clubs as well as a participation to the very first international coin bourses in Switzerland and Europe.
He has distinguished himself as one of the top experts for Spanish colonial coins. Genuineness, varieties or unlisted coins have no secrets.
During over fifty years of collecting antiques and coins, R.d.M. acquired huge experience, knowledge, and beyond improved the special “feeling” for coins that makes a great numismatist.
Coins, precious stones or objets d’art have concentrated for ages fascination and desire in all societies.
