Fiji's "Greatest Drains" series is exactly what it sounds like: fine gold coins issued under Fiji's nominal authority commemorating ancient sewage infrastructure. The Cloaca Maxima, Rome's primary drainage channel, dates to the 6th century BC and remains partially functional today — storm runoff still passes through sections of it beneath modern Rome.
These coins are struck by the Perth Mint under licensing arrangements that use Fiji's issuing authority largely as a legal convenience for collector-market novelty issues.
