All of these images are of contact marks and the mint does not use chemicals that would cause extra images on coins. Seems you're looking for information that fits what you want this coin to be and that is unfortunate.

You can achieve this same toning by leaving the coin in a cup holder of your car with heat and humidity, or wrap a dirty coin in tissue paper or saran wrap and get it wet, and after it dries out it can look like this since the tissue and wrap follow contours.

I have experimented on stuff like this all my life and I have seen just about everything someone can do to a coin, and this is not a mint error. Sorry I don't have better news but I am not tickling your ears with vague could be or maybes when I know better.
