Chinese Zhengde Tongbao Good Luck Charm or Amulet - Power, Prosperity, Harmony.  Hang this around your neck and how can you go wrong?  It is made of brass and has a diameter of around 24mm.  This amulet is round with a square in the center and has a dragon, phoenix pattern on the reverse side of it.  The Chinese lettering on the obverse is what identifies it as being from the Qing dynasty and dates itself.  Any comments, feel free and thanks for looking!
