The assertion that the 1921 shilling does not have a mint mark deserves explanation. All shillings dated 1921 were minted in Sydney and all have a small 5-pointed star above the date. However that star was not intended as a mint mark and instead was supposed to signify a change in silver content. The silver content didn't change but the star remained anyway.
