1 Dollar Theodosius gold coin

Palau's micro-gold program, launched in the early 2000s, targeted the collector market with fractional issues too small for practical handling — this half-gram piece being among the lightest gold coins produced by any recognized issuing authority. The KM#610 designation places it within a sprawling series of Palauan commemoratives that exploited the nation's monetary agreement with the United States to issue legal-tender denominated coins almost entirely for philatelic and numismatic sale rather than circulation.

Theodosius I was the last emperor to rule a unified Roman Empire before its permanent east-west division in 395 AD.
