I'd honestly want at least $250 + shipping, simply because the lens is flawless (i'd include a UV, fluorescent, polarizer filter too). Overall, I wouldn't feel right selling it at that price and would rather keep it. You can get a much better deal on eBay.
To be totally honest though, I'm looking to upgrade to the 18-200. It's more zoom and would make it so you don't need a telephoto. If you wanted more zoom, you could get a cheap FX lens and use that. That's what I do for telephoto. I did some testing with the 18-200 and you can read any reviews on it. It's just as sharp as the 18-105 but with more range.
The 10-24 Nikon is amazing (it's pretty much all I shoot now) and paired with the 18-200, you'd have everything you need for almost all situations. If you're serious about it, this would be what I recommend. The 18-105 is light and easy to use though and is very cheap used (because it's a kit lens after all, it comes with the D7000).
What camera are you shooting?
