2025 Mesa Grande 1 oz Ag Built by Aliens: Stonehendge Proof

1.0000 troy oz .999 2025 Proof

The ancient mystery of Stonehenge meets extraterrestrial imagination in this intriguing 2025 silver proof issue. Struck from one troy ounce of 0.999 fine silver, the coin belongs to the creative Built by Aliens series. The reverse design presents a striking artistic scene where a spacecraft hovers directly over the prehistoric stone circle. Adding an extraordinary physical dimension to the theme, the colorized depiction of the monument is enhanced with actual pieces of authentic bluestone sourced from the site itself. On the obverse, the coin displays a bald eagle emblem, representing the sovereign Mesa Grande nation. The surrounding inscriptions confirm the year 2025, the one dollar denomination, and the weight and purity of the silver. With a highly restricted mintage of just 1,000 pieces, this coin offers a fascinating blend of real-world archaeology and science fiction speculation.
