Notes:
The vast majority of the 7,378,973 threepences struck in 1921 bear the ' M ' mint mark and are generally of very high quality. The 1921 'no mint mark' threepences which constitute a much smaller percentage, are not as sharply struck on the reverse, which leads to the proposition that they are probably the product of dies the Melbourne Mint had adapted from a London working die. Melbourne had already used this skill in 1919 when it produced master dies for the 1919 //. Penny from a pair of London working dies. In that instance the Melbourne Mint had added a dot '//.' to claim its additional work, but with the 1921 Threepence the 'M' mint mark was removed. This was probably to accommodate a '*' being added to the design to signify the anticipated debasement of the silver content, which in the end did not occur. Evidence suggests the 1921 Plain Threepence was struck in 1922 on just a couple of reverse dies. The 1921 'Plain' threepences usually show evidence of having been struck on a rusty obverse die suggesting an interrupted production. You should expect to pay a premium for a coin with a normal looking obverse.
