Thanks for the article Bobby- I was wondering how a fake mm might be added or even created.
As someone who was involved with fraud investigations for over 30 years, it peaks my interest. I would be interested in reading more as it relates to coin if anyone has more information.
Taking that info one step further, what type of tool could be inserted into the small hole and how could it raise the precise metal to create a mm?
I know, more questions than answers. I don't know a successful counterfeiter to ask.
