Ten Cents, Coin Type from Australia - detailed information

Australian decimal coins have carried four portraits of Her Majesty Queen Elizabeth the Second.

The inclusion of an effigy of the Queen on the obverse of Australia's coinage is mandated by Regulation 4 (c) of the Currency Regulations made under the Currency Act 1965. Portraits of Her Majesty have all faced to the right in line with a convention, said to have commenced with Charles II (1660-1685), that the new Monarch's portrait would face in a direction opposite to that of their predecessor.

Lyrebird seen facing left with its tail plumes expanded forward over its head. The denomination numeral 10 [cents] is above the head of the bird; the artist's initials SD (for Stuart Devlin) are in (very) tiny letters below, in the right field beside its foot.

If you keep your coins in 2x2 cardboard holders, the best size for ten cent coins is 25mm.
