1 Dollar - Elizabeth II Hanging Gardens in Babylon

Part of a sprawling multi-issue series released around 2013 commemorating the Seven Wonders of the Ancient World, this miniature gold piece was produced for the collector market rather than any circulation purpose. Solomon Islands has no historical or geographical connection to Babylon — the territory is simply a convenient issuing authority for bullion and novelty collector coins, a role it shares with dozens of small-denomination Pacific island nations whose mint relationships are managed entirely by external private producers, most commonly in central Europe.
