3" tall with standard design Yellow Kid button #29 celluloid encased at center and held by 1/8" tall metal rim with circle of tiny "teeth." Metal frame seems to be silver-plated copper. Three small squares on edge, again with tiny jagged teeth, hold 3 inset celluloid dice. A loop below joins larger holder with larger die. All dice have additional black dots on their sides, but their original depths seem reduced a bit. The button has .25" across spot at top, similar at 10 o'clock and small, fainter marks at 8 o'clock and 6 o'clock. Button is over 90% clean. No maker name, but very high quality workmanship. Reverse hinged bar pin with locking device. First we've seen. Possibly unique.
