Does Anyone Here Know Anything About "Magic - The Gathering" Cards?..... [View all]

I recently purchased a binder of 1059 cards each in a plastic sleeve (9 sleeves to a page). All the cards appear to be in excellent condition. Paging through the binder I can see some doubles of certain cards. In a separate plastic pencil case included in the binder are the original boxes these cards were sold in. Each box is flattened to be accommodated by the case. Looks like some rule books as to how to play the game as well.

I purchased this collection because it looked intriguing to me and I'm not wondering if I have anything of value.

What can you tell me about this game? Who plays it? And perhaps the value of such a collection/cards?

Any info would be appreciated.
