The Ducat (or Dukat) is a gold coin that was used as a trade coin in Europe prior to World War I.. It weighs 3.4909 grams of .9886 gold (0.1107 troy ounces).
The Ducat was first issued in 1140 under Roger II of Sicily and depicts the figure of Christ. In 1284, the Republic of Venice issued the Ducat under the Doge Giovanni Dandalo. The Venetian Ducat depicts the Doge kneeling before St. Mark on the obverse and Jesus on the reverse. During the Middle Ages, this coin became very popular as it was easily minted and quite valuable for a small coin. During this time, the Ducat was issued in multiple, single and fractional ducats.
Ducats became a standard gold coin all throughout Europe, and more so after it was imperially sanctioned in 1566.
The Dutch Ducat of the Netherlands is the most common of ducats. It measures 21.8mm in circumference with a weight of 3.49 grams and gold content of 0.986 and was first minted by the Dutch in 1589. The obverse features a knight dressed in full armor holding a bundle of arrows (which symbolize the Netherland provinces), and on the reverse, an inscription which translates to “through concord little things grow- Holland”.
Because the gold Dutch Ducats were used as true trade coins, they tend to show wear from their long life of usage, but are still very desirable coin among collectors and private investors.
