Australia 1864S Half Sovereign PCGS VG10
One of the easier dates to collect from the early Sydney Mint series, this coin is priced as an ideal entry level piece for the budding collector. It is another difficult coin to quantify because Royal Mint records show that no coins were minted in this year. Walter Eigner suggests that coins destined for release in 1865 are dated 1864. It is another issue of difficulty in determining the number of coins available to collectors.
