2024 Austria Silver €20 Beauty of the Universe: Supernova

---

This 2024 silver coin from Austria offers a striking journey into deep space, celebrating the cosmic phenomenon of a supernova. Part of the Beauty of the Universe series, the coin is minted with 0.666 ounces of fine silver and features a unique physical structure. Its shape is physically curved, showcasing a concave front side and a convex back side, paired with a waved edge that mirrors the fluid motion of the cosmos. The front side of the coin illustrates the Crab Pulsar, a rapidly spinning neutron star. On the reverse side, a colorful depiction captures the Crab Nebula, which is the remaining debris cloud from a massive stellar explosion first recorded by observers in the year 1054. This celestial object is officially cataloged as 1952, a designation that connects this modern minting achievement directly to astronomical science. Struck in proof quality by the Austrian Mint, this 20 Euro coin has a limited mintage of 30,000 pieces. It serves as a fascinating intersection of numismatic art and astrophysics, capturing the violent beauty of a dying star in a highly tactile, curved silver format.
