a little
How old is it and what type?
pics?
With swords a good story that can be verified can raise the worth 20x and 100x if a famous person touched it.
Actual use in a famous battle can also raise it.
Pictures pretty please, and any provenance. I know crap about swords but one of the girls I work with at the antique mall adores pointy things and I could ask her, or look it up in one of the zillions of reference books downstairs on swords.
