Australia Fifty Cent Double Strike 1972

A 1972 dated Australian fifty cent coin, which after being struck, was not properly ejected from the coining press, and was struck a second time with only part of the coin still resting between the dies. Such a spectacular double strike of this large sized decimal Australian coin is very rare. Although the number of collectors of this kind of coin error is small, on the rare occasions they come up for auction they tend to achieve high prices.
