Found this while searching a can of coins. Was not sure what it was until I showed it to a local dealer. He felt it was a copper core for a dime that was stamped before the coin was finished.   |

At 1.0 grams, would half to say it must be a fake. That is about half the weight it should be.

Yeah, the planchet seems too small, but what is smaller than a dime? lol

I thought it was a fake at first, but the edge even has the ridges like a dime would. That's why the dealer thought it was a core that slipped through.

No need for anyone to fake a roos dime.
At that weight and color just might be a copper alone.
Seems to have been upset and that would cause the slightly
smaller diameter. Interesting find none the less.

It was dissolved in acid. The clad layers were eaten away.

Mike nailed it, and any dealer who doesn't immediately recognize that should close his doors, because he knows nothing about coins.
Clad coins are made by bonding three sheets of metal under heat and pressure, like smooshing a cheese sandwich. There's no "unfinished core".

If it was in acid, would the core have edges like a dime should?

The rim is reduced, so the reeding on the edges are probably gone. On some quarters dipped into acid the copper core looses diameter and the silver clad remain the same size as the original.

Depends on whether the acid eats mainly nickel (in this case) or copper. Am I the only one who sees CuNi on the reverse?
Put a zincoln in nitric acid for similar results.
Remember that acid eats all similar metal at the same rate. So it will eat both the grooves and the high points of the reeding equally.

What's puzzling is that the reeding is there.

Did you read the post above yours? Nothing puzzling, the acid eats the reeding evenly.
