How much is a Special Edition Lance Madone Worth?

So in my hours of wasting time on cycling forums I came across someone interested in buying a USPS era Madone. Not a replica, but a team issue.
I don't have anything close, but there is an unridden commemorative Lance Madone hanging in my LBS, so I asked what he'd be willing to part with it for knowing that it's been for sale for years.

They came back with a quote that floored me, keeping in mind that after the whole Lance thing, this is basically a yellow 56cm, 10+ year old bike.
Anybody out there have thoughts on its value?
