1967 Australian Twenty Cent Coin Coin.  

This coin features not only a Tilted Partial Collar Error (very rare in this denomination, BUT, also a clipped planchet! 

The partial collar error runs for most of the circumference of the coins edge (tilted), with the clip demonstrating a clear rounding of the rim near the clipped portion.

"Partial collar coin strikes occur when there is a malfunction of the striking press. This causes the collar to be in an incorrect position. The lower die (usually the reverse die) is recessed in the collar. This allows the coin which is going to be struck to have a formed rim. After a coin is struck the lower die raises upwards, pushing the struck coin out of the collar and ejecting it."

"Clipped Planchets" can occur due to feed problems or speed variations. Sometimes a set of blanks is punched out before the holes from the preceding set has fully passed. The result of this is blanks being created with some metal missing. These blanks go on to be struck and are recognised as curved clipped planchet errors."
