In general I assume Chinese cash coins have no significant value unless high grade. But just as a sanity check, here's mine:
Looks like Qian Long (1735-96). He reigned a long time, so his coins are especially abundant. Unless it's from an unusual province or a is rare variant, the value is low. I see them retail in "pick one" bins of cash coins for 99 cents. Probably get a lot less trying to sell one though...
@The Eidolon is correct, it's Qianlong. (But your photo is rotated 90 degrees clockwise.) The reverse will list the mintmark, but unless it's one of the very rare ones there's no significant value.
I thought I had the reverse imaged but I had 2 images of the obverse (unless they both look very similar and I didn't notice the difference). I'll see if I can get it right.
Reverse should look like scribbly Manchurian writing in two columns, one to the right and one to the left of the center hole. If you go to the section on Manchu mint marks on this page you can match them up to see which province minted it.
Agree that Qianlong coins are comparatively abundant. My Chinese friends saves these for Feng Shui uses.
