I'm pretty sure it's a Qianlong Boo-chiowan, as seen here: https://en.numista.com/catalogue/pieces1133.html
However, here in numista I saw that there is an option to be more specific when adding the coin to your collection, with different time frames of when the coin was made. The thing is I don't know how to do that and I can't seem to find the info online. Can anyone more proficient with these give me some help/directions?
