11/29/2011 Update: Eminem Lil Wayne to go on world tour in 2012.

Tickets for the much-hyped Eminem and Jay-Z home and home concerts at Comerica Park in Detroit and Yankee Stadium in New York were so popular that the two artists had to announce two more shows, to meet the demand of their fans. Tickets sold on the primary market, and they sold fast. Now that most tickets are sold out, the prime place to buy tickets is on the secondary market.

At SeatGeek, we wanted to see how the tickets listed on the secondary market compared for the concerts in each city. Currently, tickets for the New York concerts are in higher demand, and are listed for more money than tickets for the Detroit concerts. Interestingly, in Detroit, tickets for the first and original concert on September 3 are on average cheaper than the tickets for the second concert that was added after tickets sold out fast. However, in NY, the opposite is the case; tickets for the original concert on September 13 are listing for more than the added concert. Both added concerts are occurring the night after the first concert in each city.

If you check out the listing page for these concerts and scroll down to the bottom, you can see the average listing price for that event, as well as the price forecast, which tells you either to buy now or wait for the price to decrease.

For the concerts in Detroit, the average listing prices are around $175, but that price is predicted to increase sharply. SeatGeek recommends buying now. In New York, tickets are aggregating at an average of $374 and $313 for the September 13 and 14 concerts respectively. These prices are forecasted to increase, as well, and fans are recommended to buy now.

The range of ticket prices for the concerts in Detroit is $8250, for tickets VIP General Admission tickets ($250 at face value) to $81, for upper level tickets in the 300 section ($49.50 at face). Yankee Stadium tickets are averaging more, so the range is a bit higher, as well. The most expensive seats are listed for $22,000 each, for Field Seats center stage ($298 face value), while the cheapest listing is $153 a ticket in several sections, including Terrace Granstand side state tickets (400 level, $52.50 at face, which is cheapest tickets for the NYC concert).

There are several reasons why the tickets in New York are listed for higher prices than they are in Detroit. Generally, New York has a higher mean income than Detroit, and NY fans are more willing and able to pay more than Detroit fans. Plus, the greater population in New York means that there is a greater demand for tickets for the New York concerts than for the Detroit concerts, and the greater demand further increases the listing prices on the secondary ticket market.

Head to SeatGeek.com to get NHL Playoffs tickets or NBA Playoff Tickets! And learn how to find the lowest Stanley Cup Ticket prices.

The Los Angeles Lakers were victorious over the Boston Celtics last night by a score of 83-79, ending the Celtics season and giving the Lakers their sixteenth Finals Championship. Throughout these NBA Finals, we have been giving you game recaps, along with the listing prices for tickets on the secondary market for each game. Now that it's all said and done, we wanted to take a look back at the prices for tickets for each game, and compare the data to that of the NHL Stanley Cup Finals.

Both of these series featured two marquee match ups; the Stanley Cup Finals was between the Philadelphia Flyers and the Chicago Blackhawks. The NBA Finals was even more of a dream match up; the Celtics and the Lakers are two of the winningest and most storied franchises in all of sports. Yet surprisingly, especially given the greater popularity of the NBA over the NHL, ticket averages were greater for the NHL Finals than they were for the NBA Finals. The average ticket price for tickets for the Stanley Cup Finals was $718, compared to $699 for the NBA Finals ($633 if you exclude Game Seven).

In the NBA Finals, tickets for Lakers home games went for much more than tickets for Celtics home games. The average prices for tickets in the Staples Center in LA were $817, versus $541 for games in the TD Garden in Boston.

During the Stanley Cup Finals, the average price for tickets was greater for Blackhawks home games than for Flyers home games. In Chicago, the average was $810, whereas the average in Philadelphia was $626.

Television ratings to gauge each sports' popularity aside, it is interesting to see that fans were willing to pay more for NHL Stanley Cup Finals tickets than NBA Finals tickets. I would have expected to see the opposite, considering that basketball is generally considered a more popular sport in the U.S. than hockey.

Nonetheless, hockey season and basketball season have finally come to a close. Actually, with LeBron Mania erupting and causing the world to stop when free agency begins on July 1, basketball season is far from over. Be sure to check back with us at SeatGeek for our take on the LeBron saga, as well as for more sports news and ticketing data.
