Depends on the model, exact configuration, finish, papers, accessories, etc.. Value range from a few hundred to multiple thousands.
About $500
This is the rare one(caliber) and price reflects. $600 and up for one in great condition.
100-1000 USD or so
Unless in the exact shape, including boxes, papers, etc.. about 400 USD or so
Depends on what shape its in but $250-$300 is a good price if its decent.
With no other information the price range can be 500-5000
This almost entirely depends on the condition of the firearm and cannot be determined just by stating the caliber and manufacturer alone. That said, the price range for a Smith and Wesson .357 magnum revolver in good condition could be from 250 to 1000 US dollars.
these will range in price from 300-475 dollars,depending on overall condition,and a good bore.
It doesn't exist. I think what you are asking about is a Model 686. Price range from 150-400 USD depending on condition.
If the rifle is in mint condition and has not been fouled up in the barrel, one can expect to pay $400 to $450 at a show. Private transactions might get you a better deal. Anything in that price range though will get you a truly great gun.
Depends on its condition, whether or not the box and origanal papers and accessories are with it, etc.. Price range 200-450
200 USD
