maybe settup a website mate,  a nice fancy with all pictures of the pins and sell them like a pinball buisness would, and then drop 3 or four pins at a time on ebay, very simular to what guys like pinballshed do, as they import and 70 odd pins at a time its very simular situation to you and just sell like that. 3 -4 at a time and rest for sale on your website. might take you a year to sell them all might be quicker, but least you might make more money for them.
