Australia 1883 Sydney Half Sovereign PCGS VF25
This rare toothed reverse half sovereign is a research project. This design was phased out by the Royal Mint in 1880, yet Australia continued minting small numbers for several years following.
1883 Sydney offers the most democratic prices for collectors seeking this variant. It appears two dies were used. Look out for a blog post on the subject.
