2020 P American Samoa Quarter Possible Improperly Annealed Planchet Error

One of the members on the Coin Community Forum suggested that I post this here to get Fred Weinberg's opinion on whether or not it might be an annealing error. Any opinions would be very helpful as annealing errors are not something I understand very well.

Looks somewhat normal . The Error your talking about is just one one side .Maybe I'm wrong ?

 

@sal pretty sure annealing errors can affect one side or both, but I could be wrong about that. The coin is definitely not "normal," the only question is whether the dark surfaces are environmental damage or an annealing error.

 

I'll bet a Quarter that it's ED .

 

Here's some info from error ref,but I'm with sal.

 

Doesn't surprise me. In my CRH, I have saved a few newer quarters that are bright shiny white on one side and evenly coppery-colored (without obvious environmental damage) on the other side. The E.D. I've heard of is at odds with annealing - which removes internal stresses and toughens it!

 

@SensibleSal66 I agree that it may well be ED, but it would be helpful to point to things about the coin that are inconsistent with an annealing error rather than just asserting what you believe the correct answer to be.

I personally find annealing errors to be very fuzzy math in general, so part of the reason I'm posting this is to hopefully understand better how a coin like this can be distinguished from an annealing error (if it is in fact ED). I'd like to believe that annealing errors can be described rigorously enough that it's not just an "an expert knows it when she or he sees it" sort of thing, but so far I have never heard an explanation that I found very satisfying in this way.

For example, if someone can explain the difference between this coin (https://www.cointalk.com/threads/2017-d-new-jersey-ellis-island-improper-annealing.307775/) and mine, that would be super helpful.

 

Sam, in order to alert someone to your thread or post, you need to tag that person like so: @Fred Weinberg . @JCro57 and @paddyman98 may also want to see this.

 

Thanks @cpm9ball, very good to know! Here is a better photo of the rim of the coin, which I understand is important for IDing these.

 

I forgot to include @mikediamond . He is also one of our members.

 

The edge is the key. If the edge looks like a normal, newly struck coin then you may have something. I can't be certain from the pics, but you have the coin in hand. If you can truly be objective, then you should be able to confirm.

Based on your pics, I'm not going to dismiss it as environmental damage. It has potential, but I'm not certain. Wait for additional feedback from knowledgeable members

 

@Oldhoopster so I'm a little confused by the descriptions I've heard about the edge. The edge of mine is darkened on the nickel parts (consistent with the faces of the coin) but about as bright as normal on the copper areas. It looks identical to my eyes to the one that Fred Weinberg said was authentic in the thread I posted the link to (re posting here for convenience: https://www.cointalk.com/threads/2017-d-new-jersey-ellis-island-improper-annealing.307775/), which Fred said had bright rims despite having the same darkening on the nickel that I'm seeing on mine. I'm a little confused by what exactly is meant by looking like a "normal, newly struck coin," since to my eye the one that was signed off on doesn't look "normal" and seems to show the same darkening on the nickel portions of the rim.

Also going to re-post the more recent image of the rim that I left in another comment in case you didn't see it yet.

 

It's a good one they're all over eBay

 

So your saying yes its a.......

 

Annealing errors can be tricky.

The edges should not be the same color as the two sides. Upon ejection, the edges scrape the inner ring of the collar and the friction causes them to be shinier.

Also, the surfaces should still have strong Mint luster regardless of what color they turn - red, grey, pink, orange, spotty, etc.

Also, improperly annealed errors are seldom a uniform color on both sides.

I am leaning toward staining and not any kind of Mint error.

 

Improperly Annealed ...
I'll bet anyone on that ....

 

Anyone want to take the bet ?

 

No different it's the same as that one

 

@Rick Stachowski Thanks for your feedback! The edges do seem to be bright to me, although as I said the nickel layers seem kind of consistent with the color of the obverse and reverse.

 

The rim tells the story .
Look like it was minted yesterday .
