What Could This Be? 1951 Roosevelt With Raised Hatch Marks..

It appears it was done with a sharp knife at an angle, which pushed up the metal.
Its value is the silver content--about $1.44. If she paid more, I'd return it.

Considering the amount of ware on the rest of the coin and the relative crispness of the lines I'm leaning towards PMD scratches. But I'd like to tell you about a bit of my family history. An Uncle of mine bought a brand new car in the early 50's, there was a weird rattle behind the back seat near the wheel well, so he took it in several times and they could find nothing wrong. Finally he got sick of it and made them take the whole thing apart, I think they even had to use a cutting torch to cut into a welded panel. What did they find... well an empty coke bottle of course, put there by some bored assembly worker just for the heck of it.

Like I said I can believe it's scratches to the coin but people get bored and do weird things sometimes. I'd suggest taking more pictures, put a light at a very low angle to cast shadows, leave the light and camera in the same position and rotate the coin to show different angles of shadow... ok so I just refreshed (I need to stop taking hours to compose and read and reread) ... YOU USED A BOX CUTTER ON A 52!?!?... I hope it was an ugly one to start with.

if it was advertised as a mint error or the cost was over $1.50- $2.00 I'd take it back. If the price was fair I'd hold onto it, it is an interesting piece

@ ASLAN TVorlon,
I like the story. It's those things that make life so interesting. I was hoping it was something like that. I think if it was a mint error the lines would only be raised but the deep grooves suggest it was cut. The '52 looked exactly the same under my eye piece. Too bad.
1952...I know, it was a sacrifice that had to be made. It was out of my junk silver pile so no loss there.
Who knows, maybe that coin will create it's own story some day.

Thanks everyone for taking the time to comment, enjoying this community already!!

Probably waiting for their food in a "Howard Johnson's" Restaurant. LOL
