The Duro Boat Bird quarter staters were minted by the Durotriges around 50-20 BC, and are a continuation of the Duro Boat Gold quarter stater series. The Durotriges started minting these coins in gold but transitioned to silver as their gold stocks ran out.
This is one of eight in the collection (see 1, 9, 15, 99, 100, 110, and 118).
