Hi, I recently inherited
a coin collection from all over the world, including lots of gems from Indonesia occupation money, and VOC 1700's coins, but there is one "coin" we can't work out. Attached is some photos of what we cannot figure out. We think the markings are Chinese, and think it is an old form of trade / coin. It is made of silver. Perhaps it's not a coin at all? Can anyone help me please? Cheers !
