A quarter with the heads-side painted yellow!
I discovered it at work while finalizing this morning's bank deposit for the crafts store.
I felt compelled to take it and swapped one of my own quarters for the sun-colored one.
I love the way the letters and profile are (for the most part) visible with only the background painted. It almost looks like it was created that way.
Who knew 25 cents could have such an impact!
