Reminds me of a slug. The remnant of a hole punched in a metal box, plate whatever.

I'm aware of electrical box slugs. But dime sized copper? Last I know they are galvanized steel or now plastic. In a 7 yro cent roll. Stumped

The electrical slugs that I have seen have a tab where the metal was still attached--I don't see one of these on this object. The metal flow on the edge shows that it was sheared from plate stock. I suppose that it could be an unstruck planchet of a foreign coin, but unless we can find a close match on alloy, weight, and diameter, I would just assume that you have a blank made in a machine shop somewhere.

 The first photo shows gentle curves at the edge. The second photo shows a sharper cut. That and the metal flow lines definitely indicate a punch from a strip. Four questions:  Does this appear to be brass, rather than bronze? Would you be willing to check specific gravity on this? Would you be willing to measure the thickness? Would you be willing to measure the diameter? I wonder if this could be a blank for either a brass button or for a trade token. It's interesting. |

Don't have a mic to check diameter or thickness but weight is 2.6. Specific gravity ? Test for that? A rub on the edge I made appears to be copperish, could be brass maybe. A way to test for that ? Brass I assume would have a ring to it when dropped no ?

Here's a post I made a while back with a step-by-step to do a specific gravity test. There are a number of brass blanks made for jewelry purposes, too. I wouldn't be surprised if this is in that category. It's an interesting find in coin roll. |

If this was a future coin, it is still a blank. A blank that has run through the setup process is then called a planchet. Size looks wrong for cent. (too small) And it is not a clad blank, making it not a dime blank either.

Just throwing more out there, as it does resemble a coin blank. If it is coinage material, it would most likely be that of a foreign coins dimensions.
More food for thought. I've seen punched washers missing there center cut out or holes more than once. Thanks, Doug.

I keep coming back to the possibility that this is a jewelry blank. The photo could be an optical illusion, but the blank appears to be very close in size to the dime. Dimes are just under 18mm in diameter (17.91 mm to be exact). The photo shows that the blank is quite thick, almost identical a struck dime. A dime is 1.35mm thick. If this is 11/16" in diameter (17.46mm), 16 gauge (1.29 mm) thick, and brass, it would look a lot like this jewelry blank. Change the blank from burnished brass to antiqued brass, and it would be almost a twin. |
