I've handled numerous Experimental Planchet State Quarters in the past 18 years. This is not one of them, I' sorry to say,.

Typical, common, worn or overused die.
I can tell that, as mentioned, it's crud or wax, even from the small area photo. It is not an error coin, and larger photos are always welcomed,...
Chemically treated. Not an error - It did not leave the Mint like that. .....sorry......
An attempted hole. It's damage, not an error.... ...sorry
