Recent auction sales seem to run $400+ for pre 1940's, some as high as $600. As a hex you'd perhaps look at another $50, add a bit more for an original sling and a bayonette. .. all that being on a day where there is no one looking to fill in a collection. I've seen some recent Ukrainian imports in the $400 to $500 range in commercial settings. If advertising it mention that its a dragoon, and the arsenal of manufacture .. both add a bit of cachet - Tula made the fewest dragoons. Another note is if its got a bayonette that has matching #'s that should add to the value as most became disconnected from their original guns either in battle or in refurb.
