McCOY POTTERY -- SMILE (HAPPY) FACE CUP / MUG

This McCoy listing has a lovely smile face mug! It’s a pretty dark yellow color with black eyes and mouth and is marked on bottom: McCoy (in circle with lines), USA. It is in super condition -- looks new and unused, however it has a teeny production (1/16") McFlaw on the handle. At first glance, I thought it was a ding but the teeny piece was fired onto the back of the mug!
