Hello guys,
I need help here on an Australian Penny dated 1923( too bad it isn't the acclaimed half-penny).
It seems that the letter S on the word Australia on reverse side has an apostrophe, the design & trajectory of the foreign object suggested to my point of view that it resemble of an apostrophe...Can anyone here help me to clarify if there's such a Penny that ever existed or have exist...I could be wrong on my view & dumbfounded on this coin...can anyone here please help me & englighten me on this coin.
