Copper slug / update: Flattened coin

I found this last year and thought it wasn't much. I've looked at it a little more and question what it is. There's no marks than I can see. It's .062" thick.

Looks like a worn out copper coin. Unfortunately, we find them a lot.

Hard to believe I found this going through my change can. It's definitely a coin, albeit a one in very bad shape. I think someone flattened it. There's places I can see numbers & a star at the bottom of the bottom pic.

So if its scrap anyway, use an acid that eats copper. Coat both sides and let it sit for a few minutes. Rinse and repeat increasing acid time until features show up. When a coin is pressed, the low spots are compressed more than the high spots making the metal a little harder. The acid will eat the softer metal a little faster than the harder metal, often showing enough detail to ID the coin, if it's a coin. I haven't done this with a copper, but have been very successful on silver.

There is a few little details that would help ID the burnt copper (burnt from the soils of time) I have seen also some pretty good results from throwing the coin in a tumbler as it does a clean up of the surfaces to highlight the detail left. Weigh it also and you have the measurement just look up the size/weights of the more popular early copper coinage American/British 17th-18th century.

Also consider holding at a low angle to light and looking w/ a magnifying glass.

Excellent idea! It weighs 9.2 grams, same as a large cent. Since it's been flattened, size won't work.

I always do that. Sometimes a lite coat of spit gives the highs a little sheen too. Nothing works on the one. I wonder about what looks like a small star at the bottom of the one pic. Also, I see either "one" or "locate side".

A few pics in the sun

Damn, maybe my eyes are playing tricks, but I almost can see a "V" or "W" at about 1130 and an "E" at 1230 in the second picture.

I've looked at it 20 times today trying to figure it out.

 

[smokeythecat]

I also see the "E".

 

[metaldiggr]

I'm I seeing things or do I see "Jade"?

 

[metaldiggr]

I put what I thought was a tiny star at the edge under my generic microscope and got this. It looks like two arrows crossed?

There also appears to be a faint rim above those letters. Unfortunately I don't think enough detail remains to ID. Perhaps the diameter and weight will narrow the field of possibilities.

I can see "ONE" written with the bottom of the letters towards the center of the coin and the top along the edge. Gotta admit, this one has me working overtime to figure out.

I can clearly see "Jade", token of some sort?

This is quite a coincidence. I found a copper slug the other day.



And if you think staring at it has you seeing things like that "E" at 12:30? I swear I see an "A", "G" "L" and "E" after it. Maybe it's the drugs I take.
