The tilt of the B to the right makes me think this is 1799 obverse 4, which was used on varieties BB-156, 157, 161, 162, 163, and 164.

The reverse for 163 looks close, but we just don't have a good enough reverse pic. If the reverse matches none of those varieties, we may be lucky enough to have a counterfeiter who took impressions from different coins and mixed them up.
