Got this in some change from the store... I always look at my change before I put it in my jar and this one is obviously different.

Post mint damage. I find coins like those often in rolls.

Its a coin that has been submerged in a strong acid or other corrosive material/liquid, i have seen hundreds if not thousands of these while collecting. Most current U.S. clad coins consist of an inner core of copper, with outer layers of a silver-colored nickel-copper alloy, when they are submerged in a corrosive material/liquid the inner copper core sandwiched between the two layers of nickel-copper alloy begins to be corrode first leaving the hollow cavity around the rim.

Yup, beach coin. Want a few hundred more?

I see a lot of dimes like this one, just throw it back into the wild.

 

[AU24K]

I've got one of those myself.

I always thought it was a lamination error.
But what do I know?

Best Wishes,

Looked like someone took something and dug the outer layer off of it.

Soaked in acid?? Copper corrodes away quicker than nickel.
