Rare Elmer Sperry Silver Bar Ingot $350 This rare Elmer Sperry commemorative silver bar is a highly collectible vintage ingot minted by the Madison Mint as part of their Great American Inventors series. The front of the bar features a striking high-relief design, showcasing a detailed portrait of Elmer Sperry, the prolific inventor known for the gyrocompass, alongside a scene depicting naval officers and a ship's deck with a large cannon, symbolizing his significant contributions to maritime and military technology.
