1956 'M' Australian Penny - Extremely Fine/About Uncirculated - relatively common for period
The 1956 'M' Australian Penny is considered relatively common for period, with an approximate total mintage of 13,872,000.
It was minted in Melbourne, Australia.
I would grade this example as Extremely Fine/About Uncirculated due to the presence of much of the original lustre and design.
