Do you know if this jar should have seams?
Yes they should. The mold they blew the bottle in was hinged so it could be opened and removed. The exceptions are free blown bottles and turn mold bottles. They have no seams and no embossing. Here is a turn mold wine bottle. With radial lines from being spun in the mold. Easiest to see when you look thru the bottom. Cool circular pattern.

And the turn mold horizontal "lines" are usually very easy to see like on this bottle.

The fruit jar, not the wine bottle, will have seams even if it's hand blown because, as Robby just said, the metal is blown in to a hinged mold. There is another type of mold blown bottle that will not have seams, though, and that is a dip mold. That is a mold that looks like a cup. The cup is smaller than the finished bottle because the glass blower blows a gather in to the dip mold, then removes it and expands it further outside of the mold. The dip mold might have a rib or diamond pattern which gets expanded. That is where the term "pattern molded" comes from.
