Pictorial Charm Item Number: Edz4170 from the MOA: University of British Columbia
Round, square hole in centre, inner and outer rims on both sides, four Chinese characters on obverse, design of dragon and phoenix, both very simplified, on reverse.
A coin-like charm, which could have circulated; not from the period it purports to be from.
The representations of a dragon and a phoenix or a "double dragon" chasing a flaming pearl are most commonly used auspicious images in any context in ancient China. It is not restricted to a particular class (Li, Min).
