2001 Australian One Dollar Coin - ERROR COIN - DOUBLE RIM CUD REVERSE
This 2001 Australian 1 Dollar Error Coin features a Double Reverse Rim Cud!
A CUD occurs when a part of one of the dies that strikes the coin actually breaks off. When this broken die strikes a coin the result is a new raised feature (usually looking like a blob) on the surface of the struck coin. The blob mirrors the incuse feature on the die where the die broke.
