The ducat was a gold or silver coin used as a trade coin in Europe from the later middle ages until as late as the 20th century. The Dutch Revolt gave its seven northern provinces control of their coinage. The collapse of the government of Francis of Anjou in 1583, however, left them without a constitutional ruler to name on those coins. They fell back on the longstanding regional tradition of imitating well accepted foreign coins. In this case they avoided political complications by copying obsolete coins. The gold coins Ferdinand and Isabella issued to the standards of the ducat were widely copied and called ducats. They also imitated the Hungarian ducat and those coins had more influence on the subsequent coinage of the United Provinces. Since the Netherlands became a dominant international trader, the influence of these ducats was global.
On the obverse is a standing knight with a sword and pineapple, and a shield beneath the feet. The reverse bears the inscription MONOV AVRIA CIVITA CAMPEN.
