Coin contains 13.78 grams of gold (0.443 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 496,501 struck between 1920 and 1936. Four ducat coins dated 1915 are still being produced by the Austrian Mint as official restrikes.
