I've seen a ton of iPod Nano 5G's with the video camera on craigslist going for about $60-$85 in decent condition and accessories, it really just depends on what accessories are included with the nano and condition, you said it only has one scratch, so it is basically in very good condition for being an iPod Nano 4G. Though I would probably sell it this month, before September 8th, because when the Nano 6G comes out, it will be 2 generations old, so the resale value will go down. My advice is to sell it for at least about $60, I don't know if your selling it on eBay or Craigslist but you could probably get more on eBay. Perhaps $65-$70? It all depends on what it comes with.
