The ducat was originally a Venetian gold coin introduced in 1284. In a short time, the ducat was copied in many countries, and was first minted in Christiania (Oslo) in the 1660s. Before the introduction of the gold standard in 1874, gold coins were minted in Norway only in the 1660s and the 1670s.
