Looks like someone shattered George's head. I thought it was some pond scum or something, but its part of the coin. I was then thinking shattered die, but most of the lines are not raised, but definitely not indented. Then I saw what looks like a flower! 2020-d Salt river quarter. weight is normal.
best pictures my scope can get. That last picture you can see what appears to be a flower shape. That is very slightly raised. That cannot be done post mint. I should have mentioned to that looking straight down on this is hard to see the marks. Once light hits from an angle, the entire quarter glows with the design.
ANYTHING can occur post mint. After 37 years studying coins and errors I've seen everthing! The composition of Clad is Cupro-Nickel and can look strange if some post mint alteration is done to it. I'm thinking somebody could of hit it with an electrical current. That would affect the clad. If it can't occur during the minting process then it's definitely not a mint error.
The other statements about no need for more photos because it’s post mint damage. Just a tip. Please include photos of the whole coin if you want opinions. Those who grade coins for a living look at the whole coin and then the details. Nothing but close-ups is annoying.
Just a tip! These guys been at it a while. If you do want the images to be viewed correctly, obverse and reverse likes to be viewed. Welcome to CT.
These Microscopic photos don't help as said above. It is all environmental damage. I did not happen at the mint.
Thanks for all of the replies. The reverse side is perfectly fine. Nothing wrong with it. I’ll set up my camera with macro lens and try to get better pictures. This one is tough though because the damage is best viewed from an angle.
If you have to view it at an angle then it is definitely environmental damage, Stick it in a roll or flip and come back to it after you have learned more about the minting process and errors.
Some told me if you have to do flips and turn upside down to takes, it just may be damage. What do you think this image is? I have had and still have issues with PMD.
That might actually be closer to the truth than you realize. It does look as though some kind of liquid contaminant was on there and subsequently evaporated, leaving that craquelure pattern. I'm not sure we'll ever know what that was, and it's a moot point in any event, since, as mentioned by several, this was something that obviously happened post-mint. Which means that though it might look interesting, it's not an error.
Not an error, but just a liquid that has dried on the surface of the coin. It's environmentally damaged surfaces......
Here are better photos. I hope what I see is more visible now. I also enhanced the close up images to show the details I am looking at.
