My daughter was given a box containing literally hundreds of cards.  Most are in protective sheathes and about 180 cards in Limited Edition boxes.  How should I organize them so I know what I have?  Little symbols upper left, dark or light backs and numbers in upper right?  I also have about 170 horizontal or planet cards.  If someone wanted a particular card I want to be able to find it easily.   Meaning I only want to sort them all once.  Can anyone help?  I have no real ideas about how and where to market these or if there is a market for them.  Any help with that?  Thanks.
