20 Dollars - Elizabeth II Legacy Eagle

The Cook Islands has operated one of the world's most prolific numismatic programs since the 1970s, issuing coins under New Zealand's currency agreement that bear legal tender status but are produced almost exclusively for the collector market. This particular fractional gold piece belongs to a long-running series of export issues that generate foreign exchange revenue — the Cook Islands' actual circulating coinage is a separate matter entirely.

At 3.11 g of .9999 fine gold, the specification matches a one-tenth troy ounce, a format that gained traction globally after the American Gold Eagle popularized fractional bullion denominations in 1986.
