1952 Perth Penny Varieties

Hi all

I've finally been going through my 1952 Perth pennies to sort out, and hopefully find, a few more of each of all the varieties. There could/should be 4 or 5 ? - according to my Feb 1966 Australian Coin Chart booklet which clearly illustrates the standard issue and varieties.

I have never seen any of these 1952 Perth pennies in better then aEF.

I've been hoarding these for many years and as a result of going through
many of them, I have found that there is a distinct variance in the position of the Dot after the last " A " of Australia.

The Dot on a few of these pennies are slightly smaller - not from any wear - than what they are on the majority of these 1952 Perth pennies, and I figure at this early stage of checking that the varying space/gap between the Dot and the last " A " of Australia could be synonymous with each of the varieties of the " 2 " in the very unusual minting process of these 1952 Perth pennies..

Has anyone else checked these 1952 Perth pennies closely in the past?

Perhaps Novel could share some of her welcomed wisdom.
