This vintage 14k gold charm is a replica of a chuck-a-luck, which is a game of chance played with dice. Two dice are kept inside the device that is shaped like an hourglass that resembles a birdcage that pivots about its center. When turned, the dice travel from side to side within the cage. The bottom is clearly stamped 14k. Please refer to the photo. This charm weighs 2.9 grams and measures 5/8" in length x 3/8" in width. It is very good condition with the normal small scratches and dings due to usage and wear.
