I suspect this may indeed be an antique that has been aggressively cleaned and so I would not pass it along anywhere for just a 'nominal' amount. Eighteenth / nineteenth century seem reasonable as noted by others above. The steel is a little too defect free to try and argue for much earlier, but the Turk's head of the grip appears very well done and with wear and patina in the seams.
In my very early collecting days I had a rather renowned gun dealer denounce an espada ancha I had acquired as a modern made-up piece and my own general library book level research seemed to confirm this. Fortunately I kept it as years later - in the same dealer's shop! - I found a book that made clear that it was the real deal and something to keep.
