Mystery copper

[oxbowbarefoot]

I was cleaning some old coppers and found this one. It measures 23 mm and weighs 7.8-7.9 grams. The planchet is quite thick at 2mm. The rim is thicker than the center and the edge isn't perfectly round. The integrity of the copper seems pretty good. But for the life of me I can't make out any details. Anyone have a guess? I found it at a site that produces coins ranging from 1600's through modern.

It's thick like a Liberty cap or Braided hair. GL on getting an ID! Have any pictures of a flash light casting a shadow along the high points of the coin?

Messed with some filters to try to bring out details, not sure if these are any better...

I can't help at all,

I don't have my calipers handy, to compare that MM size to some coins I have, but when I did some web searches on early coins, I found a good report:

It was an archaeology dig at a Pennsylvania tavern. They found many dozens of 1700s coins, and many were ID'able, and a shocking high percentage of them were counterfeit.


So they did metal lab tests on the fakes, and some were cast and some not. They said the cast ones were made by making a quicky mold from a real coin, and as casted metal always shrinks on cooling, the cast ones are a tick smaller OD, and sometimes the thickness and roundness was not correct.

Interesting that there were so many things mixed with copper, on this batch from PA, to cut the cost of making fakes. One coin was so high in zinc, that it was actually now brass. I have a slick that fits this ID, but I keep reading on web that perhaps Irish coin tokens were brassy. IDK

So far its closest to a very early half cent, but it's still more than a gram too heavy. Counterfeit is definitely possible.
