Here is a 2015 P New York State Quarter with unusual PMD damage. I have looked through a ton of rolls of quarters and have never seen this type of PMD before. Obviously, some type of chemical or acid! The reverse close up has serrations possibly because the individual wiped the surface with I am guessing was a paper towel. Look at the pics and let me know if you have ever seen this before. It upsets me to see this type of destruction to a coin! Regards to all.     |

 It looks like some liquid or glue that dried up with bubbles. Have you soaked it in acetone? |

This is not a substance dried on the surface. You can feel where the indent is on the surface of the obverse and the reverse.

if the unusual color is not due to a contaminant on the coin's surface, what are you proposing are the cause of that color?

I hear you @all, but it really looks like dried glue to me too.

I stand corrected! The acetone took the material off both sides of the coin. I should have done it first as the surface confounded me! Regards to all and thank you for your help and suggestions.

Glue has caught most of us the first time.  Now you know for the next time. One more thing acetone will not remove all glue. In that case use water. |
