$703 was the highest sold on Ebay from 2013 (Boston Pinball)
$550-$650 average (Pinside est.)
I'm going to say $1200 to the right collector - if you can find one. Or, perhaps auction it off and see where it goes.
Quoted from Grayman_EM:Greybeard there was a 1970's pin listed that was a one owner with only 4000 plays on it. The person was trying to sell it for $3,300.00. I am not sure if that was just made up or true to the great condition as it looked brand new. Hope this helps.
Trying? Did they ever sell it and what did they actually get for it?
