MastroNet, a huge auctioneer of sports memorabilia, sold a Rock-ola World Series machine for $46,835.00 in December.

From a MastroNet press release:

A nickel brings the players to life in this arcade classic. The buyer had to put in a bit more to purchase what is generally considered the finest baseball arcade of all time. The mini-stadium sold for $46,835.00.
Some sports collectors have too much money. Although owning a historical machine like this would be cool, I can't imagine dropping almost $47,000 for any game or... well, almost anything really.

This auction also contained the Bartman foul ball that "ruined" the Cubs' chances of getting to the World Series last year. It went for $106,600.00.
