🔎 UNIDENTIFIED Anybody know old Chinese coins?

Found on 1800's abandoned village. I believe i have matched the left side of coin,(lower left picture of the coin) to the "boo" character form the other image and on this website https://primaltrek.com/guide.html (which seems to be a pretty decent guide) Which means Qing Dynasty 1644-1911, can anybody narrow it down?
i can try to clean the "back" more. or get some calipers out. but for now it looks like 7/8 inch (22.225mm) and weighs 3.34 grams.

The bottom right image (coin front) is very difficult to read. Is the coin's tongbao side (coin front) the correct way up? The "man" script writing side (boo) is the correct orientation. If you flip the coin over in a right to left direction (or left to right) the tongbao side should be the correction orientation.
