Very rare (no one I know has seen one before), silver amulet with a rat (definitely not a mouse). 2020 is the Chinese Lunar Calendar for the Metal Rat so this being a silver piece represents a full 60 year lunar cyclical completion this year. In Chinese society the Rat is considered clever, cultured, shrewd and intelligent although a bit manipulative (Mark Zuckerberg is a Rat). The reverse side wishes the owner “May you live 100 years”. In Hinduism the, the Rat aka Anindya is the vehicle for Ganesh. This is high quality Qing Dynasty, hallmarked silver and will polish up nicely if so desired. W: 38mm and H: 27mm. Included is a fine 9.25 silver chain, total 13 grams and free shipping.
