1 Dollar - Elizabeth II Stephan IX

The "Stephan IX" attribution here is almost certainly a catalog error or issuer misnomer — the mid-11th-century pope is properly recorded as Stephen IX, reigning only from 1057 to 1058 before dying at Florence, likely of poison. Cook Islands gold miniatures of this format were produced in quantity during the 2000s by the Austrian Mint under contract, a prolific run of sub-gram issues that flooded the collector market and left premiums almost entirely dependent on spot price rather than numismatic demand.
