Normally I wouldn't bother anyone about a brown dime...However I'd like to get some opinions on this 2005 P dime a coworker found and wanted me to take a look at. What struck my curiosity was the appearance of copper color on the surface, particularly on the reverse. I couldn't see a fleck of gray/silver nickel anywhere on the dime when I looked at with a loupe. It has a normal weight at 2.26 grams. I'm thinking if it's worth more than ten cents it would be a copper wash/improperly annealed planchet error. Looking at it some more since last night, I'm starting to lean towards it being tarnished/toned by dirt or chemicals, but I'd like to have some more experienced, knowledgable error collectors' opinions on it. Worst case scenario is that I learn more about what not to look for in rolls and change. Hope I'm not wasting anyone's time with this.
It's a spender so toss it in the change jar. No wait, on second spend it so you won't ask again in the future.
Not sure where you're located. But in South Florida a while back we had someone, electro plate a bunch of dimes. All I know is the ones I put back in circulation had big scratches across. So there could be no doubt they were fake. At the time I'm sure there were a bunch more out there in circulation. Here's the old thread you may be interested in https://www.cointalk.com/threads/01-p-10c-missing-something.278308/
I live just outside Orlando so it wouldn't surprise me at all if one ended up circulating in my area.
With all the tourist in our state. It could be extremely possible. I was lucky I found about 18 of them. And quite a few of them gave me the signs of the plating. But I also had several that you could not tell. As you can see in my old thread. But other members have given you other options, and good ones to. Hold on to it. The next coin show that's up in Orlando if you have a chance take it and have someone look at it. But we can already tell from the weight, it's definitely not a missing clad layer.
I also have a brown 2005 P dime. I'm unable to weigh it. However, it appears to be thinner with a slightly smaller circumference when compared to other dimes. I don't think that it is brown because of an environmental result. I did an online search and came across this inquiry by GUN METAL. What are the odds that both of these dimes turned brown after minting? Has any professional information come forth regarding this dime?
