Personally I will like to see a photo with correct color of the coin.

First view it is not far from your guess. Look like, a better photo will be well appreciate. If it is will be a coin for 35 to 120$

Is your coin an improperly annealed coin? I'm not sure, not my area of expertise, but to my eyes, it looks like environmental toning to me.

Improper annealing or plating used to be called Sintered planchets or plating. It is thought that during the annealing process pure metal molecules, as in copper, migrate to the surface of the coin and form layers. Add to this some heat and oxygen and coins can become reddish, black, and spotted from oxidization of the purer metal.


I will clean a little bit in acetone to see the results. On those coins which are clad coins with cooper core in the case of improper annealing we have to see the cooper color of the particles come out but.

Please try to clean and we will see the results.

The same effect like improper annealing was confirmed for some fake coins marketed under this error. I thing is better you take all the necessary steps to be sure what you has.

If the second set of photos show the true colour of your coin, it has environmental toning/tarnishing/staining.

I've had this coin for a couple years and have dipped it in acetone before and it does nothing I can do it again and take pictures of it if you need me to but I'm for sure that it does nothing here is a picture of the reeds

If you already put in acetone, I do not thing it is necessary second time.

I put up here the explanation of the improper annealing. You have the "baby" (in lab we say babies for the coins) in your hand and see better then any photo in the word.

By experience in this kind of error, the like on effect was done by counterfeiters with mild heat. Others explanations for your coins I will let the most experience folks, me I touch my expertise not others.

For Quarters, coins with improperly annealed planchets will typically show dark brown coloration, like the coin above, but can also tone deep purple or have spots of purple and blue and yellow. The easy way to tell the difference between an annealing error (which happens before striking) and environmental damage (which happens after striking), is that the luster of the annealing error coin will typically be uninterrupted and flowing freely over the discolorations. Corrosion will disfigure or destroy luster, but there are luster flow lines struck into annealed surfaces.
