Australian King George V Gold Half Sovereign Coins
Half sovereigns that have the portrait of King George V on the heads side were struck by three mints in Australia between 1911 and 1918. Whereas gold (full) sovereigns were struck according to the amount of gold that was discovered in any one year, half sovereigns were only ever struck according to the amount of economic activity in the region they were struck in.
For that reason, the George V half sovereigns from the Perth Mint in this era have lower mintage figures than those struck at Melbourne and Sydney. Half sovereigns in this date range can vary in price from a modest premium over their gold value to many thousands of dollars.
A complete set of Australian half sovereigns struck during the reign of King George V includes 9 coins - 5 from Sydney; just 1 from Melbourne and 3 from Perth.
