10 Dollars - Elizabeth II Ancient City of Petra

Petra was issued as part of a wave of "Seven Wonders" themed collector silver that flooded the market in the mid-2000s, mostly through European trading houses targeting gift buyers rather than serious collectors. Cook Islands served as a convenient issuing authority — its coins carry legal tender status without requiring domestic circulation, a arrangement that has made it one of the most prolific novelty mint vehicles in the Pacific.

Secondary market premiums on these remain modest at best.
