$150-$250, depending on condition and the exact manufacturer.
------------------------
check Cabelas for a new one. used ones are going to be going pretty cheap unless there in excelent condition even then you'll be lucky to get a $100. the 1858 Remington model has the top strap and is better if you plan on shooting it a lot, brass frames don't hold up well either.
If you're going target shooting or even using it for hunting, the brass frame will do just fine. I own five .44 cal. 1858 Remington New Army Revolvers, three brass frames with one being the Bison and two steel frames, and I paid $20.00 for a brass frame about 30 years ago and the rest I got within the last two years to present and paid $150.00 - $275. 00 each for them. You can get them at gun shows at around $150.00 for a good used one to $300.00 for a new one and even up to $600 + on a fancy engraved one. An original 1858 Remington will set you back around $600.00 +.
depending on overall condition $150 - $200
