The back of this one has a sticker that says it is from Chaeng Sen In North Thailand in the 19/20th century. We are currently in the year 2564 in the Buddhist Calendar, So this amulet is 650+ years old. they were collected in the 1990s, and I had assistance getting a number of related pieces identified and verified by friends and business connections I had at that time. Some, like this one oh, I bought a number of examples that were excavated together and had custom-made amulet cases made for some of them. most of my amulets were sold in the late 1990s and early 2000s, but as I prepare for retirement and I go through everything, I'm finding small treasures like this one.
