Looks like a fairly recent item out of a small 'hot shop' (glass blowing studio) to me , with beading around the neck & perhaps an applied 'coin' with an imprint .
The bottom appears to be ground a bit too , something done to hand-blown items & not so much for mold-blown ones ...
Seems like a useful , decorative hand-blown item , rather than an old antique , esp since there's pretty much perfect condition(s) on it .
