Brace yourselves, college football fans. It will cost big time to attend three of the biggest conference championship games early next month.

The action kicks off Dec. 2 with the MAC and Pac-12 Championship games. But it will be three of the following day's games that own the most expensive ticket prices this season, however, as the SEC, Big Ten and ACC games are each posting massive demand on the secondary ticket market.

Secondary tickets are those purchased from primary sellers -- a sports franchise or stadium -- and resold for a profit. They can often be far more expensive than tickets sold on the so-called primary market. 

On TicketIQ, a ticket search engine that pools tickets and data from over 90% of the secondary market, the average resale price for the SEC Championship tickets at the Georgia Dome is now $676.59. In addition to being the most expensive conference championship game this season, it is the top-priced SEC Championship game since 2010, when TicketIQ began tracking resale ticket data. It trumps 2010's game between South Carolina and Auburn, which averaged $669 per ticket. The cheapest tickets are currently listed from $211 each.

The SEC is arguably the country's toughest conference and features the top-ranked team in the country and defending national champion Alabama. 

Alabama will face Florida in the title game. If the Crimson Tide wins, it will likely be one of four teams to compete in the end-of-season playoffs. 

The Big Ten game will be the second most expensive conference game this year. Big Ten Championship tickets on TicketIQ now average $267.23 at Lucas Oil Stadium in Indianapolis. The cheapest tickets to the Big Ten game are now $81 each. The game's two participants have not yet been determined. A total of seven teams in the conference's two divisions still have a chance to play in the game, including Michigan, Ohio State, Wisconsin and Nebraska. 

Camping World Stadium in Orlando will be the site of this year's ACC Championship game next Saturday. Tickets are averaging $163.41 with a get-in price of $46.Clemson will represent the Atlantic division for the second straight season. North Carolina, Virginia Tech, Miami and Pittsburgh could all finish first in the Coastal division and meet Clemson for the title. 

At the other end of the price spectrum, the Southwestern Athletic Championship game will take place at NRG Stadium in Houston. Tickets average $76 and start from just $36 each. Alcorn State has already qualified for a third straight appearance while Grambling State and Southern are tied atop the West.

Grambling and Southern own 8-0 records and play each other in one of college football's most historic rivalries later this week.
