A deformed 1834 British silver coin found at a car boot sale may preserve evidence of a rare minting accident nearly 200 years ago. Advanced 3D scans and microscopic analysis revealed unusual metal distortions. ScienceDaily reported the findings on November 11, 2026. The distortions suggest the coin was crushed under extreme pressure, possibly during its original production. Researchers have not said how the coin reached the car boot sale.
