According to Warchant.com, each division winner was given 10,000 tickets to sell by the conference. Last season's matchup was pretty uninviting. It was Florida State against a 6-6 Georgia Tech team that finished in a three-way tie in the division with North Carolina and Miami, both of which were ineligible to go to the ACC title game. The conference title game was in Charlotte, which isn't an exciting destination for too many people.
So Florida State sold just 2,033 tickets, according to Warchant.com, and the stadium was less than half full for the game, which actually turned out to be a very competitive 21-15 win for the Seminoles. Although the ACC helped cover some of the expense after the first 6,000 tickets (which are all Florida State's responsibility), FSU's final expense on unsold tickets was $440,491.
