What is the value of a 1912 Australian Penny?

Answer 1

An Australian 1912 bronze Penny (George V)(minted at Heaton - mintmark = H), uncirculated and in absolute mint condition could fetch up to $875 AUD. If it has been circulated but still in good condition, it might fetch anything from $1.50 to $160 AUD.

There were 3.6 million minted.

An Australian 1912 bronze Penny (George V)(Proof)(minted at Heaton - mintmark = H), uncirculated and in absolute mint condition could fetch up to $60,000 AUD.

A reputable coin dealer will be able to give a more accurate valuation.

Answer 2

With the possible exception of traders tokens (with the traders business name on them), there were no "Australian" pennies minted prior to 1911.
