found this in circulation. Just wondering if anybody knows if this coin is an error coin or not. It looks all copper. Is it missing both clad layers? If it is then it should weigh a lot less than a normal dime. I just had it weighed and it is 2.3 grams which is full weight. IS it possible for a dime to have a full weight copper core planchet? Here is a couple pics.   *** Edited by Staff to Add Year / Mintmark / Denomination to Title. Titles are Important! *** |

   Edit: I'm just throwing this out there. Is there a chance that it is a copper colored spray painted dime? The combination of the weight and its seemingly flawless appearance makes this a possibility? Pretty cool find. Look forward to what the pros have to say. Any chance of getting a photo of the edge of the coin? Check out my counterstamped Lincoln Cent collection: http://goccf.com/t/303507Edited by chafemasterj

well theres the expensive way to find out and the cheap way, the expensive way would be to take to for Metallurgical Testing.
the cheap way would be to take the edge of a razor blade or exacto knife and scrape on the edges between reedings near the rims looking for the silver color of nickel if it's plated, it will be under it.
A 10-cent coin weighs 2.268 grams with a tolerance of ± 0.091 grams.
A single dime clad layer weighs 0.40619g ± 0.05721g, you'd double that for both sides,if it was missing from both sides, however if the sheet was missing both sides of the nickel cladding, before it was rolled to spec, it would still be spec thickness of the clad dime, the copper would be rolled to that thickness along with the rest of the sheet. weight won't necessarily answer the question so to speak, only if the cladding fell off of it after rolling.
it's not a cent planchet, it wouldn't fit into the dime collar.the cladding is 75% copper, 25% nickel. I dont' think, especially on a dime, there would be much weight variation if it was all copper and missing the cladding before rolling.
My personal opinion, it's copper plated. I see some silver at the rim above RIC of AMERICA on the reverse,and a spot between the branches on the olive branch near the top in the pictures.

I think the options include (1) environmental damage/toning and (2) plating. From the pictures, it appears to be a toned coin, but maybe the picture doesn't capture it well. A dime struck on a copper cent planchet would be a broadstrike (see below) and be overweight. I can only find one example of a dime (1964-D) struck on a copper dime planchet, which requires the copper sheet to be run through the wrong planchet cutting machine and then to be used for the wrong coin.  Picture was originally posted by Coop and comes from Heritage Auctions |

Thanks for the help...I scraped a little on the reeded edge like Big-Kingdom said and it looks to be
plated with copper.

The razor blade test makes sense.

it is 2.3 grams which is full weight I think that if it is the correct weight, then it is unlikely to be an off-metal strike. "If you climb a good tree, you get a push."

'2.3' grams not accurate enough to determine if copper plated in high school lab experiment or not. need accuracy to at least two decimal places of a gram.
Despite the above,
I suspect thin copper plating of a standard coin.
Clad coins often develop a copper toning with in ground burial after a couple of years, but toning in this case does not suggest this.

Try a mark on the reeding to see if it was plated. Of no gray color is seen it might be a missing clad.  The place to watch for would be the color of the copper area and the tops and bottom of the reed to see if any gray color is present. |
