Solid Silver Cowrie -China

This one is a bit of a mystery. I have not seen mention of this type of cowry. It appears to be well oxidized silver and stained from contact with other substances. It is solid and does not have a hole but attains the form of a shell, if not exactly the cowry. If authentic, this could be an issue of the Wang Mang period of coinage reform experimentation or another form of gift/grave cowry. 25 x 14 x 4 mm; 7.79 gm
