China(?) Cash coin

Hello,

I was hoping someone might be able to help with this one.... It was in an unsearched lot I bought a while back. I know the pictures are not great, but it is very worn. It is 24 mm in diameter, and weighs 3.5 grams. The coin is very thin, only about 1 mm, but maybe that is due to how worn it is?



Thanks,
Jeremy

the coin is China cash from the Qing Dynasty 1735-1796
the obverse upper and lower characters are Emperor Qian Long
the reverse left and right right characters are boo [unreadable], which denote the mint name
see https://en.numista.com/catalogue/pieces36378.html for a sample coin and possible mint

Thank you so much! I tried narrowing it down, and this is one of the coins the Maktun coin app suggested, but it was one of several, so I was hoping someone on here might have an idea!

The mint looks like Boo-su to me:
