The best sources are those who have nothing to gain from you.\n\nI'd begin with the Beckett Price Guides -- they come out every month as well as a Beckett Baseball Plus and Beckett Football Plus, which is larger, (has more cards).   The Plus comes out every two months.\n\nBeckett also has an online service.   There's a fee, but you can do an inventory on your cards.   That's something to consider if you have a LOT.\n\nWhich of the cards is most wanted depends on how hot the player is today.   Mark McGwire today, is not as "wanted" as the year he broke Roger Maris' record.\n\nRyan Leaf was most wanted when he was drafted, and well, you know what he's worth today!\n\nOne final thing -- don't be so quick to sell your cards.  If you're new at this, you might get taken advantage of by an opportunistic dealer.   Or, you might price the card too low, or sell it before the athlete peaks.\n\nAnd, if you're like most collectors, you didn't start buying cards for the money.   They have sentimental value, and believe me, as the years go by, those rare cards will increase in value.

You have to be more specific. Such as what year is it? What's the number on the card. But the card probably isn't worth that much. I wouldn't get my hopes up.

its a nice card, and they[ card companies and dealers] would have you think  it's a treasure[ unless you are trying to sell it to them]  but there are a lot around... how many "chips" do you think you can get off 1 bat... a thousand?? and consider the language, "....A bat used in the ws"... there must have been 100 bats used legitimately in the ws, and often the card companies make arragements for a player to use a diffrent bat each time at bat and maybe 1 bat for every swing in practice before the game... they hold special games jus so players can keep changing uniforms evey inning , then they sell the uniforms or pieces of them as "game worn".... i saw it on "60 minuts" or some show like that.\n  all that said , it still a cool card to keep and pass on to your children... anyway ive bought plenty of cards like that from dealers for $5... and i'm sure i overpaid.... yes feel good you got the card  keep it in good condition for your grand children.

Probly the first thing you want to do is buy a baseball becket(a card pricer) and see if the cards are in there. I hate to break it to you, but most baseball cards are worth a penny a piece. To be honest, i thought that the really old baseball cards were worth hundreds, but in my local baseball card shop, they were a nickle each.  But there are some cards that are worth many thousands of dollars. I suggest going to your local card shop and have someone there look at them and have him tell you how much they are worth.(My dad always says:"there only worth as much as someones willing to pay for them.")

Take the stack to a local card collector store.\n\nAsk them to see how much they are worth.\n\nKeep a mental note on which cards they tend to look at the longest.\n\nThey will usually give you a low-ball offer.  Don't take it.\n\nTake the cards they look at the longest and then search on Beckett.com to find their value.

If its in mint condition...they'd probably give you around $50 at a card colector's store.I know because i had a Randy Johnson 3000th strike-out card....and they gave me $55 for it.

Listing has pictures\n10 - 1991 Pedro Martinez Upper Deck Rookie Cards\n $55.00\n\nI've seen some cards only worth one cent but this was the highest I saw. I don't know what card you have or the year or the quality but here is what I found.

Unfortunatly not much.The late 80's and early 90's saw the overproduction phase of baseball cards start.Cards like Fleer,Topps,and Donruss from 1990 might bring you 10 bucks for an entire set.You can usually still find unopened boxes of these brands from 1990 at flea markets or card shows for 5 or 10 bucks per box.

some collectors do, i stopped when they made too many of the same player and now there are a million different companies. try your local flea market, yellow pages, and classifieds. ebay is always on hand. if there quality cards and in good condition you should have no problem selling them.

Look them up on eBay. This shows you what actual real people are willing to pay for them. Any card magazines or their websites (Beckett for example) just tell you what they "think" they are worth. Keeping in mind that they accept advertising dollars from the very same companies whose cards they are pricing.
