Ducats are gold or silver coins that were historically used in various European countries. They originated in the late Middle Ages and became popular due to their consistent weight and purity. The name "ducat" is derived from the Latin word "ducatus," meaning "duchy," and these coins were often associated with the Duchy of Venice. Over time, ducats were minted in different regions, including Austria, Hungary, and the Netherlands. They served as a standard currency for trade and commerce, making them valuable in international markets. Today, ducats are often collected as historical artifacts or investment pieces.
