What should I price the X-box I'm selling (Selling it locally)

So I have this X-box I was gifted that was bought on auction, it came modded and in very good condition (Very minor scratches). It can run discs fine, turn on, is silent, and is modded with what seems like hundreds of pre-loaded games, as well as unreleased titles. The games (And movies) Include Early GTA titles up to San andreas, Early Tom Clancy titles, Simpson's Hit and run, Read Dead Revolver, And many more titles that suprised me. Many of the movies it contains are for kids such as The spongebob movie or Shrek 1 & 2. The console itself doesnt overheat or scream when it turns on, and has no discoloration. Has the basic shell, all buttons work.
