Trouble identifying this Chinese coin

Hey Numista. I just got this new coin from a show and I was wondering if anybody could help me identify it in Numista's catalog?

Thanks everyone. All advice appreciated.

Hello,
It's a Qianlong cash. I think the mint is Boo Yuun, but I need confirmation (I'm not very comfortable with manchu writings)

Compare with this one : https://fr.numista.com/catalogue/pieces17924.html

boo yun

Take it out the holder to take pictures.
That holder costs more than the value of the coin

​Haha, does it really? I got it for $1.

​ooops^^, you are right

It's close enough, don't worry. I saw Boo Yun / Boo Yūn / Boo Yon / Boo-Yôn to designate it as well

The character for the "u" alone has a sort of "dot" on the right, however it's a bit more complicated than that because the transliteration should be syllabic rather than alphabetic for the manchu.
