I am an amateur coin hunter for sure. Ive been collecting pennies for years, but I would not call myself a pro at knowing everything about them. But, I came across a penny that i have never seen before. I can't find anything online about it either. It is a 1994 no mint mark, with some of the coin silver. The sides are rounded as well. The research I've done notes that it may be caused by a chemical, but it does not seem that way to me. I don't know if I could post a picture, but I have some. If anyone could help that would be great.
