1 oz Cook Islands $100 Gold Armillary Coin Valcambi (In Assay)

---

The 2015 Cook Islands 100 Dollar gold coin is a marvel of modern minting technology, blending traditional precious metal artistry with interactive design. Struck from one troy ounce of 0.9999 fine gold, this piece is composed of concentric rings. Using specialized technology developed by Valcambi, these rings can be separated or twisted, allowing the flat coin to unfold into a three-dimensional shape resembling an ancient armillary sphere. On the obverse, the rings display the portrait of Queen Elizabeth II along with the name of the issuing nation, the Cook Islands. This side also records the 2015 issue year, the face value of 100 Dollars, the weight, and the gold purity. When aligned, the reverse of the rings showcases the Valcambi name written in elegant script across all four bands. This innovative design offers a tactile exploration of geometry and numismatic art, turning a legal tender coin into a kinetic sculpture.
