If it has a 6 inch barrel it's probably worth about $600 if it has a 3.5 inch or 4 inch it's probably worth $750 or more depending on if it's like new and has the box, paperwork or tools with it and then it could be worth $1000 or more but we don't know because you haven't told us anything.
If you want answers you need to provide pictures, description with facts like barrel length, finish nickel or blue, and what comes with the gun like box, tools , Etc. or we can't really help you.
