Rare/Collectible vids I have:
I, Robot #110
Major Havoc/Space Duel Conversion
Lunar Lander
Cyberball 4 Player
Star Wars Upright and Star Wars/ESB Upright
Centipede Upright with Twin Galaxies record holder Ben Carter (until relatively recently - he held records for some time) on the high score table
Paperboy
Not totally sure some of those are rare or collectible, but I don't see them around much these days
