A local gun shop had one for a couple weeks during the winter. Their asking price was $350-ish IIRC. Don't know how that would correlate with a nation wide add Gunbroker will get you. Take lots of good pictures, write a good description and headline, run the auction long enough for people to find it (preferably encompassing at least one weekend) and if you have the cojones start it at a penny. Good luck with your sale.
