It's not very old item but it's interesting to learn reverse inscription. I didn't saw charms with coin legend Ch'ing Yuan T'ung Pao.
By Gilbert Tan note (27-Apr-98) it is a fake of The Ching Yuan large cash, the only known piece which was owned by a Ching Dynasty collector. There is also an iron fake of this coin.
