Damage on Date.... How Was This Done?

[ikandiggit]

This one is a bit of a mystery to me. The date has been obliterated. There are intentional scratches on the coin but how could someone make such tiny holes like these?

There is also a hole on the obverse but in a different location. None of the hole go through the coin and there is no evidence of them on the opposite sides.

Looks like somebody dicking around with a punch or some other pointed piece of metal.

It looks like a 1947ml, with a blunt 7, that someone wanted with thr pointed 7, or the combination that is worth the most money, ans because it wasn't, it got 'riddled". It looks a lot like the corrosion that one sees on coins that have been in water for long periods of time, but the holes are too closely placed to be corrosion. The one in the head looks like a "coup de gras".

Looks like the impact of a nail driven in by taps of a hammer.

[Dick]

Mike, I hadn't thought of that, but it could be someone testing a "nail-gun". Such a waste!

[smed]

A nail gun should put a nail completely thru a coin without a problem.

[Dick]

You are thinking of the framing guns. i was thinking of the small brad type. They might do the same thing. I sure don't have any around my coins.

Whatever it is, it looks creepy

The holes are so small, I'm thinking may be a straight pin/pins.

[Dick]

I agree. that is why I thought it might be a small nail gin. i have three, (guns), that shoot very small, (diameter) nails. but then the size is a lot smaller than the smallest I use. If it was a centrt-pinch, it would have to be VERY small, and very sharp, to make the small holes.

[eagames]

Since they hit the head and date I'd suspect a bored guy with a punch.

I would think an the impact required to make these type of depressions would also produce some deformation on the reverse of the coin. Unless heat was also used - I'm leaning towards some type of chemical reaction caused the damage.

The metak on the surface of a coin is easy enough to move around with a harder metal and rather minimal pressure. It seems pretty obvious to me that this damage was caused by a sharp instrument made of a hard metal - like a titanium dart tip.

I would not be willing to go with chemical damage just because there's no damage opposite the holes...there is also no evidence of chemical damage on the coin.
