From what I can gather this seems to be a very ancient Chinese coin called Wu Shu, but I can't find the specific coin. Anyone know anything about this type?
I don't know the denomination of yours, but you can look around this section of Numista https://en.numista.com/catalogue/pieces47353.html
The first coins with this inscription Wu Zhu (Five Zhu) were issued in 118 BCE, but this type continued, sporadically and in many varieties, for about 700 years. It may not be possible to attribute your coin more precisely, unfortunately.
