25 Dollars - Elizabeth II Shroud of Turin

Cook Islands has issued commemorative gold under its own authority since the 1970s, exploiting a licensing arrangement with New Zealand that permits independent coinage while keeping the territory's population of roughly 15,000 entirely uninvolved in the numismatic trade generating their monarch's portrait. This piece is a collector product, not a monetary instrument, and was never intended for circulation.

The Shroud of Turin has been radiocarbon dated — controversially — to between 1260 and 1390 AD, a finding contested by researchers citing neutron flux anomalies from the 1988 sample sites. Swarovski crystal inlay on a .9999 gold flan is a marketing format that emerged in the mid-2000s, pioneered largely by the Coin Invest Trust operation in Liechtenstein, which supplied similar products to multiple Pacific island issuers simultaneously.
