2014 D Roosevelt dime

[Hess4]

Is the coloring on this dime just environmental damage ? I’m down to one eye for now do to an accident so I’m having a lot of trouble trying to see what’s going on. Also, I apologize in advance for any photos that are bad, having trouble with them to! Lol

As always thank you for your time and input!

Hi Tracy,

You have this one just right.....the coloration is in fact environmental damage.  You see this thing a lot on US nickels and clad coins.....the nickel in the alloys of those coins is some pretty tough stuff but the copper is a whole different story.....it's very delicate and reactive.  And, most importantly, I'm sorry to hear about your eye! I had a pretty significant eye injury about 16 years ago and it was awful.  I hope you heal up soon!

I think it's environmental, but it's kind of a weird color. I'm trying to think of a combination of copper and nickel salts that would produce that yellowish color, but am not familiar enough. Nickel nitrate is green, for example, but I can't remember about copper nitrate (which I assume exists in some proportion).

That yellowish color is what made me send it in because I had not seen it on any coins of mine , but of course I’m a newbie so! Lol. Thanks for your input, I appreciate it.

In general (I'm sure there are a few exceptions such as an off metal error, or contaminated plating solution on copper plated zinc cents)  any off color on a coin is due to environmental reasons.
