The auction has closed, and the final price was - are you sitting down? - $27,690 (twenty-seven thousand, six hundred and ninety dollars).
The story may not be over yet, though. The last 23 minutes of the auction developed into a bidding war between two individuals (the third bidder dropped out at $15,040). However, in the Facebook group "MLB Game Used," one person said that the winning bidder is a non-payer; however, another member of the group responded that he a) knows the winning bidder, b) just texted him, and c) believes he'll pay. So we'll see what happens.
But in the meantime... wow wow wow wow wow!
