Typically I try to stay away from making price predictions for players I follow, and for the most part I think it leads to a biased opinion - but I'm going to take a shot anyway. The SF Giants are fighting for a playoff spot and possibly a division title late into the 2010 baseball season and 'rookie' catcher Buster Posey is a large part of the teams success. Buster played some games for SF late last season - however his presence in the Giants lineup for the past several months have made the Giants a contender to win a playoff spot. His smooth swing, ability to throw runners out behind the plate and general 'nice guy' presence will make him a huge star in the Bay Area.

Playoff baseball is a time where some people who live on the east and west coasts respectively start to see players they only see highlights of. East coast games are on when Californians are finishing up a days work and eating dinner. East coasters are in bed by the time Buster Posey has his first AB of the night. For that reason - I think Posey's cards might have a good chance at getting some exposure. Obviously I'm banking on a couple of things happening.

1 - Giants have to make the playoffs
2 - Buster has to play good

However, if both of those happen - I feel his 2008 Bowman Chrome Draft Autograph RC Card has a good chance at going up even more than it already has. I think Giants fans will jump on board considering they have paid good money for Tim Lincecum Autographs - and east coast prospectors or collectors might like what they see too. Given the price for a non-refractor version is under $100 - that also might mean there is some room to grow. All signs point to the card going up if the team plays well going into October baseball.

Card on eBay: 2008 Buster Posey Bowman Chrome Auto

Current Avg. Price: $77.85 (4 Auctions)

Our Prediction: Up Arrow ~ 10% (Or Around $85.00 Early October)


RESULTS: The Giants ended up making the playoffs - and Buster had a nice 1st game. We looked at 11 auctions ending Oct. 2 - 7 with an average price of $87.03 - With 2 selling for $100.

eBay Price Check: 2010 Topps Tim Tebow Rookie Premiere Autograph
Time Frame: October 1, 2010

Average Online Price: $249.95 (2 Total Auctions)

Tim Tebow brought his massive fan base from his days as QB for the Florida Gators, right on over to Denver when the Broncos selected him in the first round of the 2010 NFL Draft. Collectors have been buying Tebow rookie cards from Panini and Press Pass for months but Topps released it's first set of the season on August 25th and the Rookie Premiere Autographs, serial numbered #/90, are some of the most sought after cards in the industry.

All of the RPA cards are signed on-card which is a nice change for collectors who will be bombarded by sticker autographs from Panini and Topps all season long. Two (2) Tim Tebow RC Premiere Autograph cards have sold on eBay during the first 3 days after the release of 2010 Topps and both sold for $249.95. 

Tebow is shaking off some bruised ribs he sustained when diving into the end zone for a TD in a preseason game against the Bengals. Kyle Orton is the starter for the Broncos, and our guess is that Kyle does what he always does - throw the ball short, and play tough. This will keep Tebow on the bench except for special formations, perhaps on the goal line where he can best utilize his toughness and of course, the jump pass. We see the value of his 2010 Topps Rookie Premiere Autograph #/90 going down just slightly, to around $225.00.  We will begin monitoring auctions around the end of September to see if we are right or wrong.  For the record, we at Sports Card Radio would love Tebow to get on the field as soon as possible - he is great for the hobby and anyone running a hobby store can benefit from having Tebow cards for sale.

Our prediction: Down Arrow $25.00  - To at least $225.00 By October 1st

Reported Sales:
10/1/2010 - $190.00
9/24/2010 - $190.00

Correct - The Price Did drop - even more then we expected.

eBay Price Check:
2009 Donruss Elite EEE Aroldis Chapman Auto #/695
Time Frame: March 15, 2010

Average Online Price: $61.00 (3 Total Auctions)

Aroldis Chapman recently signed with the Cincinnati Reds. Who knows how fast he will make it through their system but the hype is already behind this Cuban defector. This is his first certified Autograph RC card. Aroldis Chapman already has some Base (Non-Auto) Rookie cards on the market, and you can find a complete list by checking out our RC Checklist for Aroldis Chapman.

This prediction is for the base version #/695. I think after about 2 months the excitement behind this card might cool. Other companies may include him in a set or simpy collectors will be on to the current prospect playing well in the MLB. This one could go either way! If he is tearing up the Minor Leagues and speeds up to the Majors (which is possible) then the value would go up quite a bit. But I get a feeling that he might need some seasoning in the Minors before getting a call-up to the bigs. Therefore, I see a small drop in price. I don't see much competition, but I see other prospects taking the stage come Mid March.

Our Prediction: Down Arrow 10%  (About $6 Per Card Decrease)
