This is a vintage wall hanging of a replica of a Chinese coin which is under glass, matted and put into a wooden frame which is 6 3/4" square x 7/8" deep.  It is in very good condition and seems to be slightly different from others I've seen on ebay.  Besides the Chinese writing at top of "coin", there are dancing figures on either side of the square hole.  The "coin" itself is 3 3/8" in diameter.  The backdrop inside the frame shows more Chinese writing and the matting shows horses pulling some type of cart with Chinese figures inside the cart.
