Just looked at one on internet that looked in great condition for $795
Value depends on condtion, how bad you want to sell it, how bad someone wants to buy it, what caliber it is, any accessories, the box, original papers, etc.. Go to proofhouse.com to date it. Value range from 200-600
I just put a Lawman Mk. III on layaway at a local gun shop. It was selling for $650, but the guy gave it to me for $599. It's in great condition, as far as I can tell.
$250 to $2000, depending on its history, condition, and background
100-1000 USD depending on specifics, box, papers, etc..
