Hi guys,
Basically I purchased a bulk lot of pre-decimal coins and while I was going through them I noticed something strange about a 1941 penny I received. There appears to be silhouette of a head behind the roo.


From what I can make it, there is a clear forehead between the roo and the Australia at the top of the coin. There also appears to be the outline of a neck by the date. The coin is not in the best condition unfortunately but the head can clearly be seen.
What do you guys reckon it could be?
