Well, it's an auction, so who knows where the price will go. Buying something sight unseen is always a crapshoot.
At an auction, I always decide the maximum amount I am willing to pay, and most of the time the price goes beyond that so I keep looking. It's easy to get swept away if you don't set a limit.
It's hard to say what the value of this is...it is so dependent on your area, what the going price is, how bad you want it, and how often these show up.
