2022 2022 D Wilma Mankiller Crescent Shaped Improperly Annealed Quarter

The DATA quote:
Quote:
FRED WEINBERG: AND every single non-error has the same dark color on the reeded EDGE of the coin.

When Fred say this was at one ANA conventions back few decades. Him talk about annealing and other Mint errors and in same time Ken give an conference about toning , rainbow toning and fake toning.

Data took just a small part of what him say without look at all content.

Is correct to be nice red color when the core is new. In the case of the Delaware quarter, the color is correct for an aging cooper. Here you has to be very careful, the color. Heat after strike give a color which the cooper will never rich in normal conditions. Best way to see a cooper which was heat is the dark brown color with some nuances of blue petroleum.

The cooper colors are upon the time: red, red-light brown, dark red-light brown and brown.

Hope help you.

PS: If is fake annealing, the nickel on the rim will have same color with the rest of the nickel and not white. is what Jeff talk about, the nickel.

I found the original thread finally where I had taken the notes from. It was 2017 not from long ago. https://www.cointalk.com/threads/20...ling.307775/ I know improperly annealed planchets are difficult at times to identify properly. It appears that if the edge of the coin exhibits its true clad layers and their normal color, and does not show any signs of environmental damage on those layers, meaning that it doesn't appear to be the same coloration of the changed obverse or reverse surfaces, then there is a possibility it's a true Improperly annealed planchet which is what I was adding to the discussion. In that event you can proceed with either talking to an expert or going to a grader. This info should help eliminate some of the typical environmental damaged coins that people post.

If the information is misinterpreted or applied incorrectly then the resulting conclusion is flawed and incorrect. I've read all this info before and multiple times so I have a good grasp of what exactly is being said. The reason I say this is because the info applies to more coins that I've posted that were said to be questionable. Striation lines appear on all the coins that were in question. We should now know they are all mint errors. To be specific the ones with over heated planchets have a darker colored copper core than a normal quarter and striation lines are part of that mostly if not always. These should no longer be in question in my eyes. The diagnostics are there

@RW1010, Appreciate all the images and time explaining your findings. You will find others that have posted the same thing https://www.cointalk.com/threads/20...tern.394386/ so clearly with all these coins having the exact same issues it needs to be looked at closer to being a mint issue or something commonly happening in the processing after coin production to have so many examples. Its unfortunate that at this time there is no complete agreement among those whom we might usually turn to in hopes to answer such questions but the more info and photos, the more likely an answer will come.

@Data: long time I do not was on cointalk.com. I read this explanations time ago. Also was a part of his exponential to the conference. I will look in my database to find the conference film is very interesting because touch many aspects of this branch of collecting and errors.

@COOP: Yes the Cu change the colors upon the time. Also in air tide or seal slabs will change. Cu is second best metal for electrical and temperature accumulations and transfer. Just changes of temperature will change the color. Is no way to stop this long term processes.

@RW: Those annealing coins are Mint Error. Yes not everyone's can recognize those on the spot. More education must be done, and like this all those who fake them will be lost in the wild.
