Improperly Annealed Arkansas Quarter

Found this in my change. It's charcoal grey and has a nice luster to it.

That is not improperly annealed
Natural Environmental toning

 

How can you tell? It looks just like this.

The colors on that site are not true. Bad pictures.
It would be a Brownish Red color. You say it's Charcoal Grey which tells me it's Environmental Toning due to exposure to the elements.

 

Here's another one. Read the third paragraph.

Here's the edge of the coin.

 

Lets say you did have an improperly annealed Quarter, what gave you the bright idea to grab it with a pair of pliers?

 

Those aren't pliers, they are plastic tweezers.

 

Still you take the chance of causing enough damage to lower the grade or Details the coin.

 

My opinion is this...
Found fresh out of a new Mint wrapped roll or bag - Yes to error
Found in pocket change - No to error

 

It's just toning.

 

I will try to find the Hotsprings that I found in a bank roll.

 

Thanks to all who replied. So far the consensus is that it is not an annealing error. Keep the opinions coming. Although I've been collecting coins since I was a kid, I'm new to error coins and I'm still learning.
One thing that has me confused is that if it is environmental damage or toning, why is the edge of the quarter shiny and new? I don't know much about the process of stamping coins. So if the planchet was improperly annealed, would the stamping process clean up the coin edge?

 

Sorry to bump an old thread, but I'm still confused by this coin. If this coin has environmental damage, why is the coin edge not affected and looks shiny and new? I would think environmental damage would also affect the coin edge.

 

The nickel seems to have the same tone on rims as it does on the surfaces. It some how hasn't really affected the copper core, I would expect to see a lot of mint luster coming thru the dark tone for it to be Burnt or improperly annealed.

 

can somebody tag me. I think I have 3 or 4 burnished quarters although I can't find the Hot springs it was the deepest. Almost a chocolate purple. and glowing in luster. I will try to get some photos of them.
