Get them appraised by a local card collector.  It is a matter of supply and demand.

I don't know the price off hand.  But, you can find the current value of any baseball card on Beckett.com.  Also you might try getting a Beckett's Sports Cards Guide to help you price cards you have.  They sell them at sports memorabilia shops, some grocery stores, stores like Walgreen's or Wal-Mart, or a local trading card shop.  Look in your local phone book to find a memorabilia or trading card shop and pick one up if you have a lot of cards to price.  For the interest of just the one card I would just try the Beckett.com website.

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.

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.

I have to admit to not knowing a lot about baseball cards but the best way to find out how much things are worth is to find how much others are selling for.  Check froogle for your exact card, and possibly ebay as well.\n\n(I did a rough search and came up with a lot of different nolan ryan cards for sale from $2.oo to $450 ! http://froogle.google.com/froogle?q=nolan+ryan+baseball+card&btnG=Search  )

Yes.  Beckett would be best, but costs $3.99 a month.\n\nA good judge of value would be eBay.

I don't think there's a free website for that.  Run out to your local hobby store & pick up a Beckett's guide for baseball cards.  I think it runs monthly, but I'm not sure.

Take it to a sports collector store and and get them appraised.  You could also buy a Beckett magazine.  They have the values of cards.  It is hard to say the value of a card without knowing the year, maker, condition, and card number.
