What's up with this Jefferson nickel?
I found this nickel when I was CRH this afternoon. A normal nickel weighs 5 grams and this nickel weighs 4.7 grams the reverse looks totally normal. The obverse just shows a shadow of Jefferson. I put it under a 500x to 1000x microscope and I cannot identify any of the legends, date, or mint mark. I cannot see how this could be caused by PMD or a die that had grease on it. Any one who has any idea or has seen one like this your opinions would be greatly appreciated. Thank you for your time
