Coin Type:Australia Penny
Grade:aUNC
Year:1964
Mint:Royal Mint (Melbourne)
Obverse:Elizabeth II (Gillick)
Reverse:Kangaroo (George Kruger Gray)

A really interesting 1964M penny. The obverse at the lower right has had a cold shut fall away prior to being struck. When struck the missing metal on the obverse resulted in the 4 of the date on the reverse being completely missing! A lovely little error of a type not often seen.
