When Magic: The Gathering hit the scene in 1993, it changed the world of trading cards forever.
Finally, there was a trading card game that older kids weren't embarrassed to be seen playing. Today, 20 million Magic players around the world are still collecting and trading their cards. But even if you've given up on the game, you might want to dig up your old collection.
Certain magic cards are worth a bundle online. We've researched the average prices for 13 of the most valuable cards (in good condition) on MTGPrices. See if any of these are tucked away in your collection.
13. Imperial Seal - $550
From the Portals set, this card isn't one of the most powerful Black spells, but it's a crucial card for deck-building with that color. It's usually worth a few hundred bucks even in bad shape.
12. Time Vault - $1,100
A card from the very earliest Alpha collection, the powerful effect of this card makes it a collector's item. Despite its huge price tag, this isn't even one of the Alpha set's "Power Nine" cards.
11. The Tabernacle at Pendrell Vale - $1,400
Part of the highly collectible, early Legends set, Pendrell Vale is one of the collection's strongest cards. Legends booster packs are considered valuable just because this card could be lurking inside one.
10. Tropical Island - $2,600
Another Alpha card, this powerful Land card is still a must-have for players with Blue/Green decks because it lets them add a land from either color on demand.
9. TimeTwister - $2,700
The first of the "Power Nine" Alpha cards to grace this list, TimeTwister was a powerful card when it was first released. Decades later it can still change the course of a game.
8. Mox Emerald - $2,900
Five "Mox" jewel cards released in the game's earliest set have become collector's items because of the huge Land boost they provide. While the value of each card falls and rises, Emerald is currently the least valuable.
7. Mox Pearl - $2,900
Pearl is usually considered one of the rarer Mox cards because its description - "Mono Artifact" - became obsolete after the game's first two sets.
6. Mox Sapphire - $2,900
Surprise! Another Mox. A few years ago Sapphire was the top dog of the five Mox cards, but it's fallen down the list recently.
