Hungary continued to strike ducats with 3.53133 grams of 98.6% fine gold. Unlike the unchanging designs of the ducats in Venice, the coat of arms on the reverse of the ducats of Hungary was frequently modified to reflect changed circumstances. In 1470, Matthias Corvinus replaced the coat of arms by a Madonna. Hungary struck ducats until 1915, even under Austrian rule. These were used as trade coins and several of the later dates have been restruck.Standard Catalog of World Coins, Chester Krause and Clifford Mishler, Trade Coinage section of the listings for Hungary
