Price check on Para

Alright, I have a para "big hawg" double stack 1911 I got off my brother that I'm looking to sell. The thing is, I have no earthly idea on how much these things go for. It's in perfect mechanical condition, but does have one scratch on the external finish. Nothing big, but you can see it without looking too hard.

I know that guns sell for different prices in different places, but I honestly don't know if this gun is worth 50 dollars or 500. Any help would be appreciated.

Mods, sorry if I posted this in the wrong section, if so would you move it?

Yeah, tried that but none have been for sale, at least under the name big hawg.

I appreciate the help, thanks guys.
