If I'm selling, sure…$1500.
If I want it sold, in the condition it appears from your pics, $500-600. Can you take photos against a lighter background? Can't tell if that forearm has been dragged or it is the grain. Also looks like possible well work bluing up top.
That full-buckhorn sight is most likely an add-on. My buddy just bought two, to supplement his Dad's and his brother's, and none have a full buckhorn. FWIW, buckhorns are the old dudes' answer to pisspoor stock sights, much like today's ghostrings.
This is one of the rifles that should be put back into production!
