Illinois Pyrite Sun, Sparta 400g No. 170

Illinois Pyrite Sun (1960s Mined) – Sparta, Illinois – Rare Pyrite Dollar Specimen One of a kind, will receive this exact specimen. Authentic Illinois Pyrite Sun mined in the 1960s from the historic coal mines of Sparta, Illinois, USA — a locality that is now permanently closed. Also known as Pyrite Dollars or Miner’s Dollars, these rare disc-shaped formations developed within ancient coal seams under extreme pressure, creating the signature radial “sunburst” pattern unique to Illinois pyrite. Unlike cubic Peruvian pyrite, Illinois Pyrite Suns form as flat, perfectly circular metallic discs — a geological anomaly found only in this region. Because the mines closed decades ago, no new material is being produced. All genuine Illinois Pyrite Suns on the market today come from vintage collections and old stock, making them increasingly scarce. This specimen features: • Strong radial sunburst formation • Natural metallic silver luster • Classic circular “dollar” shape • Historic American mineral locality A true collector-grade specimen and a rare piece of American mineral history. Origin: Sparta, Illinois, USA Era Mined: 1960s Material: Natural Pyrite Formation: Pyrite Sun / Pyrite Dollar Rarity: No longer mined
