The Schulman Numismatists, auctioneers in Amsterdam, have included a scarce and very rare gold coin minted in 1982 which commemorated the 200th year of Dutch-American friendship that will go under the hammer on the 29th and 30th June. It is understood that the 50-gulden coin was presented to President Ronald Reagan for the occasion of the state visit of HM Queen Beatrix and HRH Prince Claus, which also marked the 200th year of friendship between the two countries
