2022 2022 D Wilma Mankiller Crescent Shaped Improperly Annealed Quarter

I am leaning towards toning not annealing.

Agree with JimmyD--given the posted pics.

Fred Weinberg described how to tell a true improper annealed coin from simple environmentally damage. Every single 'mis-annealed' coin that someone has shown him at a coin show, or in an email, that turns out to be environmentally damaged or played with, has a darker duller surface than it should have, AND every single non-error has the same dark color on the reeded EDGE of the coin. So you need to see an edge photo. It's a good authentication point to check, if you're not sure of a 'darker' color coin is truly mis-annealed/improperly annealed, or has been played with after the coin was in circulation. Although mis-annealing leaves a range of 'darknesss', seeing the reeding as a normal red copper color is one of the keys to know it hasn't been played with.

if it looks like a normal BU Quarter - the copper core shows a nice normal red color - that's because although the planchet itself (on a genuine mis-annealed planchet) would have the dark color on the smooth edge, once it's struck in the collar, and ejected, that dark color is removed from the reeding due to the ejection of the now-coin from the collar. This can indicate a real error ....as opposed to a coin that's been 'played' with, which will have the darker color ON the reeded edge.

Although most of the 'full' dark planchets are uniform as to the darker color on both sides, there are some that show a normal surface on parts of the coin, due to how it was laying in the annealing drum when it dried. That's a good thing to look for, but there are exceptions.

This looks improperly annealed to me. I'd be interested to hear what Mike Diamond says if someone wants to bring him in.

Your coin is showing a red color on the edge, which is the normal for copper. A darker color will be seen on the over annealed coins. Even when the coin sill show wear, the metal is darker in color because of being over cooked as a planchet.
Graded examples: (which I don't always trust as some errors they are wrong on examples I've seen or had been hood winked to believe)



Is someone heated the coin post strike, the colors would also be the same as an annealed quarter. The only way I would consider these is to find these in an original roll. Then you know they were not tampered with.
Black Beauty:






Note the outer edge of the rims show the darker color in the roll. When you find this, then you have the real deal.

Color on metal detector coins:
A metal detector coin will show a brown color on all areas of the coin. In circulation, the brown wears off the tops of the devices, showing the gray color.

The brown eventually turns black in color and the surface slowly turns gray, but also dull looking:


CoopHome: Colors on coins can be affected by their environment. May or may not be the real deal. Finding them in the original rolls in a better to know for sure that they are real examples

I'm adding the above information from Fred in an image form for my personal reference files.

Save for your educational image files.

This coin has discoloration/dark color on the reeded EDGE where the darkened area is on the face which according to what Fred Weinberg mentioned should indicate it is not an error coin but happened somehow afterwards. I'm just giving an opinion based on the information provided by others but your welcome to get their opinion directly also or a TPG. It is interesting and worth investigating further since the modern coin minting process is handing out several new findings.

Thanks Datadragon. I'm not seeing darkened areas on these or any of the other coins. I'll put some more convincing photos together in a few

Thanks for the pick up point Coop and Datadragon. All the coins have the darker copper color diagnostic. So like a black beauty nickel a black beauty quarter will have a noticeably darker edge
