We have tennis racket charms / pendants.  The listing is for a lot of 3 pieces.  They gold tone metal in the form of tennis rackets.  These came with a lot of Monet Charms from the 1980's - I do not see them marked so I'm not sure if they are Monet or not. They measure about 7/8" x 1/2" across the widest point.
