A gold ten ducat coin minted in Czechoslovakia in 1937 featuring the patron saint of Bohemia, Saint Wenceslas, has been bought in auction for a record 550,000 euros (the equivalent of around 14.7 million crowns). Only 34 of the coins were ever produced and not all survived to today. The seller had originally bought the coin in auction in Switzerland for 900,000 crowns, a representative for the auction house said. The authenticity of the coin was verified in comparison to two owned by the Czech National Bank. The ducat is the only one in the series that was ever publically auctioned.
