The 1955 Melbourne Mint Proof Penny was one of 1200 pieces minted.
From 1953 to 1955, 20000 pieces were minted with the exception of this extremely rare 1955 Proof Penny.
This makes this coin the rarest of all proof pennies minted post The Korean War.
The patina on this penny is so perfect bordering on shades of light to into dark brown, with continuing age and correct storage the coin will only add further to the value of the coin.
As a proof penny, it is prefect it every way.
We have not seen more pristine coins from 1955 than this particular coin.
