The 1962 Australian shilling was minted in Melbourne, Australia, with a mintage of 6,592,000.
This example features both a clipped planchet, and strike through error on the obverse.
"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."
A "strike through" means something was between the die and the planchet when the coin was struck and there are a number of things that a coin can be “struck through” including cotton from a rag, wire, a piece of planchet.
Comprised of 50% silver, 40% cop, 10% zinc/nick, it weighs 5.65 grams and has a diameter of 23.5 mm.
It is considered relatively common for the period.
The obverse features the laureate bust of young Queen Elizabeth II facing right, with the surrounding legend: 'ELIZABETH II DEI GRATIA REGINA'.
The reverse shows a merino ram, a tribute to the wool industry. The encircling legend reads 'AUSTRALIA' above, with 'SHILLING' and the date below.
I would grade this coin as Extremely Fine.
