Dime W/ Smooth Frame, Not Sure What This Is.

to the CCF!

@aluminum12, first welcome to CCF. Second, it could be a coin that has rolled around in a dryer as Buddy suggested or just a whole lot of wear as cotw mentioned. In any case, the value of this coin is still just ten cents. Keep it if you find it interesting--otherwise just spend it. Thanks for your question!

It's not natural wear but it's not necessarily a Dryer Coin either.

You can tell it's not natural because the design isn't sufficiently worn especially on the reverse; the "wear" is concentrated on the rims and periphery of the coin.

By some means the rims were removed. They could have been unintentionally removed in a dryer or other sort of device or they could have been intentionally removed with a file, grinding stone, or even a knife.

The rim protects the coin from wear and allows it to stack. Once all this metal is removed the design wears extremely quickly. But until it's worn flat again the wear appears to be unnatural and the coin will sit of it's design on a flat surface. It won't stack because it sits on the design and rocks. Extremely worn coins do the exact same thing so eventually you can't tell removed rims from wear. But you can on this coin and you can tell the rims were removed.

The coin appears to have been in about VF- condition when this damage occurred. Most likely it happened in the mid to late-'80's. The scratch probably came before the more serious damage.
