I bought my two a couple of years ago for $800 each, and they have gone up in value. It's rare to see them come up for sale, and the only ones I could find on either Gunbroker or Gunsamerica were the brown laminate stock type, all at what I paid for mine. The black laminate stock, shot, with a few dings, would be an easy sell, but may not bring that premium. Spook1 tried to sell one in the classifieds a while back at $975, but I'm not sure if it ever sold. Start at what you paid for it since its used, see what happens.
Good luck with your sale.
