5 Dollars - Charles III St. Gaudens Double Eagle

Cook Islands has issued a long-running series of fractional gold pieces that use classic American coin designs under licensing arrangements, with the St. Gaudens Double Eagle among the most frequently reproduced. At 0.2 g, the gold content is negligible — this is fundamentally a novelty item, not a bullion instrument. The denomination of five Cook Islands dollars has no meaningful purchasing power on the island territory itself.
