Pictorial Charm

Design similar to a coin, but too large to circulate; not from the period it purports to be from. (Larson, David)

The representations of a dragon and a phoenix or a "double dragon" chasing after a flaming pearl are common auspicious images in any context in ancient China. They are not restricted to any particular class. (Li, Min)

Round, square hole in centre, inner and outer rims on both sides, four Chinese characters on obverse, design of dragon and phoenix, somewhat simplified, on reverse.
