Cerveny 686 BBb sale question

[tubaman1019]

I own a Cerveny 686-4MR BBb and I plan on putting it up for sale soon after I get my Miraphone 1292. It's in very good playing condition, with a few dents on the bottom bow and a little ding on the bell. Slides all work perfectly. Little lacquer wear on the first valve silde and on one of the bends under the top bow. I bought the horn new for about 4k in 2007. What would be a reasonable price for one of these horns? I'll work on getting some pictures up. Thank you all in advance.
