Notes:
The 1922/1 Overdate Threepence is a controversial coin appearing to be an early experiment by the Melbourne Mint to alter the date on a die. It is thought that in this instance the last figure on a working hub was simply hammered flat and a new figure was roughly re-entered on the ensuing die while it was still soft. Melbourne Mint had been experimenting with die work on pennies as early as 1919 and on the dies for the 1921 silver threepences and sixpences from which it had removed mint marks, but this would appear to be the first time that it attempted to re-enter a changed date on a Commonwealth coin. It is known that in 1922 the Melbourne Mint did not have the figure punches needed to alter dies, so either the mint fashioned its own tool to attempt the task, which would account for the crude result, or these unrecorded coins were struck in February, 1923 when the punches became available. What is certain is that this overdate is the product of just one experimental reverse die, as all examples have the same diagnostic pimple of metal in the reverse field at the juncture of the legs of the kangaroo. This rarity is usually found in only ‘Very Good’ condition and so this 'marker' may not be always apparent on heavily worn examples.
