10 Dollars Cloaca

Issued under Fiji's external coin program — which licenses the country's sovereign authority to private minting houses, primarily the Perth Mint and the Austrian Mint — this piece belongs to a class of numismatic product that has nothing to do with Fijian monetary history and everything to do with the collector novelty market. The "Cloaca Maxima" series exploits ancient Roman engineering as its hook: the sewer system begun under Tarquinius Priscus in the 6th century BC that drained the Forum Romanum and still functions today as part of Rome's drainage infrastructure.
