Based on the title of the thread, I was expecting to see a link to some story about a serial killer in a town called Wilma! That last name is a bit jarring. Sorry, can't help with the error evaluation
Wilma Mankiller was the first female to be elected chief of the Cherokee Nation. As for your coin, I can’t tell but you may have one with die chips.
Under the ear may be some die gouges, nothing serious but a possible indication the die was worked on at some point.
