Just so you're sure - what Coopz said above is spot on.
You don't really have much in terms of card value but there are some nice designs to look at. If you're not sure just have a look at completed ebay listings to get an idea of what they're worth. Normally the key things to whack into a search are the Product (Select, Totally Certified, Prestige etc), the year / season (2014-15 etc), the subset (Hardcourt Heroes, Prestigious Pros etc) and any numbering ( /99 etc). If any of those are worth anything then you need to look up the player and scale value accordingly.
