If there are any they would be on the tang under the grip. The fact that yours has a pinned on grip, as I remember, means it is likely to be a hand forged blade which makes it a much nicer sword than the machine made versions and adds a bit of value as well. How much I don't know, since I'm not sure what they are selling for but it would be worth researching, especially if it's a signed blade by a desirable maker.
