Gold Austrian 4 Ducat 1915

The Gold Austrian 4 Ducat is one of the worlds oldest and purest bullion coins, containing 98% gold content (23-carat). This coin is dated 1915, but was re-struck much later - it should therefore be considered as a bullion coin, rather than a numismatic collectors piece. It is still a remarkable coin however, with a thickness of around .7mm. Franz Joseph I features on the obverse of the coin, with the coat of arms of Austria and a double-headed Imperial Eagle on the reverse.
