Leaving out lots of detail and nuance, Feng Shui relates to Chinese good luck and prosperity, and I-Ching is an ancient Chinese system of divination. This token captures both concepts: Feng Shui in the four Chinese characters on the front and I-Ching in the octagon-shaped bar patterns on the back. These are very popular good luck pieces and are often tied together with colorful ribbon to enhance their appeal.
These are all modern pieces, manufactured in recent times and sold to tourists, collectors, and as gifts. A single coin in good condition might sell retail for $2 to $4 US dollars. If you have one to sell to a coin dealer, expect an offer of 10 to 25 US cents.
Requester Panicos references an eBay auction for a Feng Shui I Ching coin where the starting bid is $500. If it sells, the seller will walk away with a cool $499 profit.
