They are Japanese charms which are widely-reproduced and sold by many "feng shui" stores and on eBay. Do a search on "tian bao di bao" for examples and pricing. Gary
I've seen some of those charms on Japanese auction sites. A group of 4 charms, including yours, went for the equivalent of $14 in one recent auction. In another auction, the charm alone was being offered for a starting price of $14, but nobody bid on it.
