ModernCardGuide.com provides real-time pricing for graded football, basketball, golf and hockey. Because this price guide site is driven by auction sales in order to get a true value of a card, instead of just a guess or estimation, they do not have baseball values yet due to the huge volume of baseball card sales each day.

Although this is a pay-for-use subscription site, they do have a unique way to let you use the site for free. After initial registration (5 day free trial), whenever you are going to purchase anything from Ebay, simply log into the card site and click the Ebay logo or links. This "click-through" take you to Ebay and anything you bid on and win while this new browser is open will earn you credit which is automatically converted to free subscription days. Pretty cool concept if you ask me.
