Cool blue dime!!!!!!!

Well I was going through dimes trying to find some silver dimes.. rather then looking at dates I turned them all vertically so that I could view the edge of the coins.. seeing many clads I was beginning to give up then I notice one cool clad dime... instead of having a brown and grey edge it had a blue and gray edge.. all the way around. the edge of the dime was half blue and half grey! astonishing! It probably isn't worth anything because I'm guessing it's just tarnish but still I think the coin looks beautiful with the blue add-on
Check it out! 3 photos below.

possibly corrosion depending on where it has been left.

 

I've ran a few dimes through our oven at work (~500 degrees) and they turn a purple/blue color in spots. Maybe the edges were exposed to heat?

 

When you say they turn blue.. Do you mean like this?

 

Wow! That is an old photograph. Almost didn't recognize my own work. Here is the update photo which is a more accurate representation of the actual coin.



BTW, I no longer own this coin!

 

How much did you sell it for... Do you know what caused the blue.

 

IIRC I sold it for $80 to a member of this forum. I don't know what caused the toning but I can say that it is a very common color on silver Roosevelt Dimes. Here are some more.





I was working on a blue toned Roosevelt registry set but have since abandoned the project.

 

I'll just jump into the blue'ness




but I'm not entirely sure what would cause the rim to turn a solid blue like that.

 

That's the word I'm looking for... RIM! haha

Also the rim looks like its tarnished blue.. I don't know.. I have a bunch of really cool toned coins like the blue dime above except on the obverse and reverse not the rim.. I'll post them in a bit! (ex. silver pennies, gold quarters, rainbow nickels, black pennies.. etc.)

 

I hope you don't hold all of your coins like that. Tsk! Tsk!

Some copper compounds turn blue when hydrated, so It's likely the copper corroded.

 

Only the circulated ones.

 

Here's another cool blue (and green!) dime from late last year:

ah,. you're right.

 

Did somebody say a blue dime?????

 

I would say similar but not exactly. It was a while ago I did it. If I remember I will run a few more through tomorrow and post them tomorrow night.

 

heres another in hopes of seeing more

 

I have one which is dark green to black blueish but from 2005D? Is it interesting? Looks like the above one. The color is equal on entire surface on both sites.

 

People are going to tell you this thread is 8 years old. Doesn't matter to me.
Generally a color like blue or green on a "clad" dime (mostly copper) is not going to be a good thing. Always try to include clear photos of both sides and the edge (if nec.).
