The 2026 Niue Jupiter from Callisto 1oz Gold Proof Coin is an exceptionally limited modern numismatic release, with a worldwide mintage of just 99 coins. This example is individually numbered 26 of 99.
Struck from 1 troy ounce of 99.99% pure gold in proof quality, the coin features a dramatic view of Jupiter as seen from its moon Callisto. The reverse combines the immense scale and colour of Jupiter with the surface of Callisto, creating one of the most distinctive space-themed gold coin designs of 2026. (APMEX)
The obverse features the effigy of King Charles III, together with the Niue 2026 issuing details, $100 denomination, weight and gold purity. The coin measures approximately 38.6 mm in diameter and is supplied in its original presentation packaging with its numbered Certificate of Authenticity.
This particular coin is in as-new condition and has also been independently weighed and tested using a Sigma Metalytics precious metal verifier, with photographs provided for additional buyer confidence.
With only 99 examples produced worldwide, and this being the highly desirable No. 26, this is a genuinely scarce opportunity for collectors of low-mintage gold coins, Niue issues, astronomy-themed coins and premium modern numismatics.
