how much do you think a 1992 shaquille o'neal rookie card would be worth right now????.(he was on the Magic.!)

It depends, if the card is in perfect condition then you could sell it from $50.00 to $100.00! If it has some scathes and folds then it would range from $25.00 to $50.00! That has been said by the best baseball card trader the world.

Not a lot considering there is a 1986 card of him out there that is worth much more. The '86 Bonds is from the Topps Traded series and is worth almost triple the value of the 1987 card. The 1987 Topps, though, is worth around $10, but I would sell high on it now and invest in another card because the value of Bonds' cards will go down with all of the controversy, much like the McGuire and Jose Canseco cards have.

You could go to http://www.beckett.com but I'm not sure if you can look up cards for free.  Ryno was my favorite player as a kid and I still have his rookie card in mint condition.  It used to be worth a fair amount but last time I checked it was only about $12, so don't get your hopes up.  Good luck.

You'll have to post a picture of it, look it up in Beckett's basketball card book, or take it to a shop and get it appraised. You could also take the more practical approach by selling it on ebay. However much someone pays for it, that's what it's worth.

On Ebay, people are asking $200-400 for similar items (SB signed balls, bats, jerseys) but I don't see anyone getting them, a signed ball from 1998 only went for $12.50. I would say your cap would be worth $100-150 if he actually wore it in the game, less if it is just a cap you had him sign for you.

Take it to a sports and memorabilia appraiser.  If there's an auction house near you, they should have one.

I looked a little more about this for you and found this story about the pink jersey. Sorry it's kind of lengthy, but tells it all. Enjoy!\n\nThe Mystery of the Pink Jersey\n\nMike Laga amassed 423 career AB over the course of nine seasons between Detroit, St. Louis and San Francisco.  He had a .199 career average, and is probably best known for being the only player to have hit a baseball actually out of Busch Stadium (A foul ball left the park in September of 1986).  \n\nBut for me, Mike Laga will always be remembered for something else: The 1987 Topps card which depicts him wearing an airbrushed-pink jersey!  \n\nIn all my youth, the closest baseball cards came to perfection were those ’87 Topps.  Sure the early Upper Decks were nice; and I won’t sell the 1988-1989 and 1991-1992 Donruss sets short.  But those ’87 Topps had that special something: the perfect mix between action and posed photos.  The player-name box was tastefully understated.  The team logo was just the right size.  Many remember that set for the wood-grain frame that brought it all together.\n\nThe answer to the Mike Laga question has eluded me for years.  As a boy I wondered “why is Mike Laga wearing a pink jersey?”  Later it became “why would somebody at Topps airbrush a guy’s jersey pink?”\n\nMy first thought was that it might be an error card.  I hoped that something had happened when the film was being processed that botched the photo.  Error cards are worth a lot of money, right?  My 1981 Fleer Craig Nettles is an error card, and at one point it was worth $5.  $5!!!  I’ve got 800 of these Mike Laga cards, I might be rich!\n\nMy sister and I must have spent an entire summer trying to track down the 1988 Donruss Mark Grace rookie card; or the Fleer Billy Ripken with the dirty word on the knob of the bat.  I knew error cards were worth a lot of money (to a nine-year-old), and so when I saw that the ’87 Mike Laga was worth a mere $0.03, I quickly dismissed the notion that it was a true “error card.”  \n\nOne possibility is that Topps used a photo from Mike’s time in Detroit, although my first instinct is to reject this premise: the Tigers did utilize the three-band strip of elastic around the neckline, but the Tigers jerseys of 1986 buttoned-down (unless I am mistaken; admittedly I am not an authority on the history of Tigers uniforms).  The photo of Laga clearly indicates a jersey without buttons is being worn.  \n\nPlus, baseball card photos are traditionally taken during spring training, right?  Mike got dealt to St. Louis in 1986, so they could’ve easily snapped another photo of him during spring training of 1987; or they could have easily taken an action shot from the end of 1986.\n\nEven if this was a modified photo of Mike Laga in a Tigers jersey, it differed from what Topps would typically do for this situation.  For example, the 1988 Topps Doug DeCinces (card #446) features DeCinces in an Angels uniform having rounded second-base and possibly watching a play develop at third.  Across the top of the card the name “Angels” is spelled out in block letters, but in the lower-left corner of the card in 6 or 8 pt black type is written “Now with Cardinals.”  If the only thing that Topps had available for Mike Laga was a 1986 photo of him with the Tigers, why not simply note in the corner that he is “Now with Cardinals,” like they did for DeCinces?  \n\nI do know that card companies pay players for their photos (although in the 1980s it probably wasn’t much).  Did Topps not want to pony up an extra hundred bucks to pay Laga for a new photo?  If they felt that Mike was such a marginal player, why include him in the set at all?  In any event, the total costs of detailing a Mike Laga photo in 1987 probably far exceeded that of just paying him the $100 for a new photo.     \n\nAlthough the Mike Laga card is a mystery, it is not my favorite card in Topps set of 1987 (no disrespect to Mr. Laga).  My favorite was al

my best guess would be to go to a dealer and ask them or see if you can find a price guide sort of like the ones they have for sports cards

depends on what year..but if it was in his early career i'd say like $40.00 or $50.00...the baseball card industry and prices have fallen dramatically ever since eBay happened.

First of all, I'm not a sports card buyer from Boise Idaho.  I am in fact a interested sports card buyer from Pennsylvania.  Do you have any football cards you are looking to sell?  I understand that you are looking for help on how to determine the value of your cards.  If you have any football, please let me know, maybe we can do some business.  I'm a honest man, don't want to be cheated and don't want to cheat you....meaning the value of the cards.

eBay is a terrible place to assess value for anything other than the most high-end, hard-to-find items. Buy a copy of Becket Baseball Card Monthly, the standard for card prices. \nI agree with the above poster about the umm, design for the 1987 set. However, I would revise the valuation upwardly to, perhaps, around $50, based mostly on the strength of the McGwire card and the growing appreciation in prices of 1980s sets. But definitely check this with BBCM.

For the Manny Ramirez and Roger Clemens rookie cards, it depends on which series you get.  Certain series are more valuable than others.  I believe that the 1992 Gary Sheffield rookie card isn't that valuable because Don Russ is not a particularly good series and I believe that 1992 was not a particularly valuable year for rookie cards. The 1992 Donruss Gary Sheffield card is not a rookie therefore it can't be worth that much. Also, how valuble these cards are depends on the condition and if it is graded. I looked up the 1992 Donruss Gary Sheffield card on ebay and I found 49 cents and $2.

It depends on which ones they are and what year. Are these basketball cards? A '98 Jordan is worth about $5.00. I would guess off hand that what you have is worth between $1.00 and $15.00. \n\nA collectable is worth what someone is willing to give you for it.

Mine's retired, It's MJ, the secon on the list's also retired and it was another MJ (Magic Johnson), I'm not an old school guy, I'm just 24, but the basketball played from the early 80's till the mid 90's was the best for me (remember the dream team?)

I think the Rose card is worth 10 cents, maybe 12!!! Schilling's rookie year was in 1988. You can check is stats here.....   \nhttp://sports.yahoo.com/mlb/players/4267/career;_ylt=AvtBu4Ww7d9LQjnTT_u_glqFCLcF

to be honest probobly not a whole lot. You would be surprised.  A handfull might have some kind of decent worth, but for the most part the card collecting business has changed from yesteryear.  Card collecting these days really hinge on the auto card, or the game used jersey card.  I really knew this when I bought a 1977 Franco Harris for 2 bucks go figure
