The floating branch is a die polishing error. Fairly common on Mercury dimes, particularly S mint ones. You might notice "die burn" (a mirror-like patch) in some of the polished areas.
I see quite a few marks, but I don't see any clear wear and plenty of luster, so maybe MS62 or so. I see bridging on the central bands, so not quite FB.
