1975 No Mint Dime More Interested In Reverse

Yes, post-strike damage.

Damaged, spend it. Worth 10 cents.

The edges of the scratch are raised.

Had it been a strike through an object would be pressed into the coin by a solid block of hardened steel under many tons of pressure. The surface around the area in question would be as flat as it is on a normal coin

100% damaged - a deep scratch

And once again, for the newcomers: there is no such thing as "mint damage". There's "damage", also called "post-mint damage" to emphasize that it's not a mint error, and there are mint errors and varieties - some of which can look like "damage", but they're not called that.

In this case, the issue for debate is whether that ugly gash across the reverse is a mint error (strikethrough) or merely an ugly gash caused by somebody vandalizing the coin. In this case, the evidence is clearly pointing towards the ugly gash theory.

When a sharp object like a screwdriver or knife is scraped across the surface of a coin, the furrow created by the blade pushes metal out, creating "ridges" of metal either side of the furrow. These ridges are clearly seen on your coin. With a strikethrough, there isn't any actual displacement of metal, so no such ridges are created.
