Every Magic card belongs to a set (an edition), marked by a symbol and a three-letter code printed on the card — for example M21 for Core Set 2021 or CMR for Commander Legends. The same card name can be printed in dozens of sets across three decades, and each printing is a different collectible object with its own price.
Within a set, cards have a rarity: common, uncommon, rare or mythic rare. Rarity tells you how often the card shows up in boosters of that set, not how good or valuable it is. Plenty of commons are format staples, and plenty of mythics are worth less than a bus ticket.
On top of set and rarity come treatments: foil versions, alternate and extended artworks, borderless frames, promo stamps. Treatments multiply the number of versions of a single card, and their prices move independently. As a beginner you do not need to memorize them — you only need to know they exist, so you never assume two cards with the same name are worth the same.
The edition gap can be enormous. Lightning Bolt from Masters 25 — the exact same text and artwork lineage as the 1993 original — trades around $1.23. The original Limited Edition Alpha printing of the very same card sits around $620.00 in our catalog snapshot. Same name, same effect, a difference of three orders of magnitude — all of it is edition, scarcity and condition.
Condition is the last multiplier: a Near Mint copy and a heavily played copy of the same printing can differ in price by half or more. Before you buy or trade anything above pocket money, read our card condition guide (NM, LP, MP, HP) — it is the vocabulary every trade is negotiated in.
