Where are you located and what is your market like? The value of the speakers depends on where you are and what your market is like.
I have a pair of Monitor 10A speakers. I paid less than half of that, but I need to repair one driver. Mine came with the nice Peerless tweeters. As far as perfect condition, these speakers have vinyl covered cabinets. Generally, there are only two conditions for the vinyl: trashed or good condition, so "perfect" does not require much of a premium.
And yes, every mid-driver should have the magnet epoxied in place if not already done.
