3. Air Raid
Value: $33,400
Known Copies: 14
It was thought that only 12 copies of this games were available, and they were fetching up to $3,000. Interesting thing is that neither of them had an accompanying box or manuals. Later in 2010 and 2012, two boxed copies were found. The later one had an accompanying manual and was sold for $33,400 on Game Gavel.
