1 Dollar Constantine gold coin

Palau's "Constantine" dollar belongs to a series of fractional gold minors issued primarily for the collector market, capitalizing on demand for affordable entry-level gold pieces rather than any commemorative obligation. The Republic of Palau, a nation of roughly 20,000 people, has issued collector coinage under licensing arrangements since the 1990s — the issuing authority is nominal, the coins never circulating domestically.

Constantine I's association with gold coinage runs deep: his solidus, introduced around 312 AD, became the dominant gold denomination of the late Roman world for over seven centuries.
