One I found in China today. About the size of a silver dollar, no lettering anywhere on it, no milling or lettering on edge. On one side, a picture of a woman's face with headgear, looks like the sort of picture one sees of the Virgin Mary in old Catholic art, face framed by a wimple or some such. Picture more-or-less fills the available space. On the other, a reclining female nude on a couch, with another person or two, hazy, in the background. This picture is relatively small, does not fill the space. Anyone got a clue what this might be?
