1922 Philippines Culion Island Leper Colony PCGS VF30 PhM C/M Straight Wings

This 1922 Philippines 1 Peso (KM-16) is a deeply historic issue struck specifically for use within the Culion Island Leper Colony, preserved in a PCGS VF30 holder. The obverse is centered around a prominent caduceus, a traditional medical symbol featuring a vertical staff entwined by two serpents and surmounted by the distinctive "straight wings" variety. The reverse displays a large, central numeral denoting the denomination, accompanied by a small, circular Philippine Mint (PhM) countermark stamped directly beneath it. Offering well-defined details and a profound connection to twentieth-century medical and colonial history, this certified coin is a remarkable addition for a specialized collector.
