    Hello everyone,
    Decided to go through pennies again, it's been awhile and have to admit never should have started. Once I get coins out it's hours before I decided to stop! Anyway I came across these pennies and was curious what the heck happened? What causes the pennies to look like this? Decided to ask the experts, thank you.

    Maybe from a roll in a house fire?

    It doesn’t matter what happened, it’s damaged.

    A strong acid caused that. A clothes dryer would have smoothed it out. Do you see the bumpy surface? That's atypical in a dryer coin, but typical in a strong acid wash, such as in HCL or H2SO4.
