Hi all.
Found this Australian 1912 halfpenny missing the letter "O" from "One Half Penny" on the reverse.
I am fairly sure its a strike through grease error, but I cannot find any evidence of another specimen the same.
I'm looking for confirmation that this is the case, and would love to know if it is common to see Australian pre dec coinage with this problem.
I am Australian, have looked through quite a lot of pennies, and have not seen or heard of one.
Many thanks in advance.
