1966 Washington quarter error?

[Disc Golfer]

I see a second image besides the Washington. Is this common?

Welcome to the forum. I don’t see another image and don’t think you have an error. Whatever you think you’re seeing is likely coincidental/random.

Here is a better pic.

Your image is sideways, and the coin looks corroded to me with a scratch across Washington's head.  Maybe a detector find from the ground.  This is a copper/nickel quarter, so the metal is much more reactive to contaminants.  If you are seeing some other image, maybe you could give us a hint of what you are seeing.

Your mind is trying to make sense out of the lights and shadows of the coloration causing it to "see" something which isn't there.  It's just the way our minds are hardwired, to try and find patterns in random data.
