Looks Like Damage (Wlh) But Not Sure From What?

What is your question? Are you asking if this is mint damage? If so, it's not; it's PMD. It looks like someone scratched the coin intentionally.

Sometimes it is to "mark" the coin to see if they ever find it again, or to destroy bad memories of a terrible year, but yes, it happens quite often. We humans ain't known to be non-destructive critters, are we?

Almost all post mint damage is characterized by impression into the coin, such as cuts, scratches, pitting, dents and corrosion.

LOL Coinfrog ,I needed a good laugh today, that's real funny

It is usually difficult to know exactly what motivates someone to place a mark on a coin. But we can say several things about this one.

First, it was done deliberately, by hand. There's no way that someone could "accidentally" carve two sets of (roughly) parallel lines onto a coin, at (roughly) right angles to each other.

Second, it was not done to mess with coin collectors, or to try to trick anyone into thinking this was some kind of weird mint error. Presumably, the lines once passed across the high points of the coin as well as the low parts, but due to wear from circulation, the lines on the high parts have worn away. True, getting a knife and carefully cutting lines in the low parts while leaving the high parts alone would be an alternative explanation, but let's invoke Occam's Razor here. This in turn means that the coin saw considerable circulation after the lines were placed there. Which means, in turn, that whoever placed the lines there thought they were simply placing lines onto a coin to be used as money (rather than damaging a collector's item).

Conclusion: bored person with a knife (or other sharp object, like a screwdriver), back when these kinds of coins were in normal everyday circulation.
