Product Code

When decimal currency was introduced in 1966, the fifty cent coin was the showpiece of the new circulating coins. It alone contained silver, was round in shape, and featured the Commonwealth Coat of Arms. However, silver prices started to rise above the face value of the coins, and in 1968 the Royal Australian Mint ceased production of the coins.

The new coins, released in 1969, were twelve-sided or dodecagonal in shape, and manufactured in copper-nickel alloy. The new coin shape differentiated the fifty cent coins more easily from the round twenty cent coins. In the time since its introduction in 1969, the coins have borne five different effigies of the Queen, and a range of commemorative designs.
