1915 Austria Gold 1 Ducat

Ducats were produced in high purity gold, 23 3/4 carats (98.6% gold), making them among the highest purity gold coins ever issued for circulation. Because they have inherited their design and appearance from medieval gold coins, they are very thin compared with modern coins, at just 0.8 mm thick. Coin contains 3.44 grams of gold (0.1106 troy oz).

Ducats were issued by Austria in 1612, and probably earlier. The last regular issue of ducats was in 1914. All the ducats dated 1915 are restrikes, of which there were 996,721 struck between 1920 and 1936. One ducat coins dated 1915 are still being produced by the Austrian Mint as official restrikes.
