1966 10c Coin Split Planchet Error
A split planchet error occurs during coin minting when a metal blank (planchet) splits due to internal flaws, improper alloy mixing, or inadequate annealing. This weakens the metal, causing a separation before or after striking. Such coins often display missing design details, irregular shapes, or rough surfaces along the split.
