How would I price my Sony lens?

(I'm not sure if this is the correct area to post this... If not sorry)

I'm thinking of selling my Sony 18-200mm 3.5-6.3. The lens, new, goes for $530 on the Sony website

The body of the lens is in great condition; a very small amount of the lettering is scuffed off (by that I mean on two letters there is a little paint missing from the letter). The glass is scratch, haze, and fungus free (from what I can see), but has one piece of dust on the inside (which doesn't effect picture quality)
I would include a Quantaray UV filter ($10-20 new)
Has original body/back cap, but a different lens cap

Im gonna assume you dont have the original box and everything either.

Price it at $450, but be prepared to accept something in the $350-400 range.

Nah, no box. I got it with the camera (a100), and I got the camera used.
I'd be okay with that though, thanks
