Any indication of the event or who the other guy(s) are in the photo?
$250 doesn't sound too off to me if it's a Type 1 (perhaps top of market unless the event is significant and I'm just not recognizing it). I would still like to hear other opinions though as I find my sense of true "value" is a bit off after a long summer of slow eBay sales and selling mostly mid- to low-end material. Takes a little while to readjust my barometer. Ask Ben if he would buy it at $250, and then if he says yes, snatch it up quick before he figures out where you saw it
