Trading Cards

Pokémon, Magic, Yu-Gi-Oh! and One Piece, played or kept:

the four games that fill most binders all release their sets in booster packs, but they hold value differently. Pokémon is collected for the artwork, and its illustration rares sell on looks. Magic: The Gathering prices follow play in formats such as Commander, so an old card can jump when a new deck needs it. Yu-Gi-Oh! prices track the tournament format most closely, and with official regional qualifiers held in Belén, competitive staples sell on what that format wants. One Piece, Lorcana and Riftbound draw smaller groups, and sports cards and World Cup postales follow their own rules of player, year and numbering. The Pokémon and One Piece figures that often turn up in the same box belong under action figures.

Sealed product, singles or a graded slab:

decide first whether you are buying to play, to open or to keep. A player spends less buying the exact singles a deck needs than opening packs in the hope they appear. If you open for fun, open from a sealed display, not a loose pack of unknown history. A collector who wants one card at its best buys it graded: a slab from PSA, CGC or Beckett records authenticity and condition, and the grade sets the price. Language counts too: Pokémon is sold here in English and Spanish and Magic has Spanish packs, but English prints are the easiest to resell abroad, so a Spanish card of the same rarity usually fetches less.

A ₡4,000 booster against a card quoted in dollars:

a single Pokémon or Yu-Gi-Oh! booster costs around ₡4,000 new, and a sealed 36-pack Pokémon display runs to about ₡90,000. Once the pack is open, what comes out is rarely priced in colones: many singles sellers in the country quote in dollars, because a card’s value follows the US market and moves week to week. Sealed product goes the other way: packs from sets out of print for a decade fetch many times their original price.

Whitening, resealed packs and fake slabs:

judge a used card by its back first. White specks along the edges and corners are the first wear, scratches across the holo foil come next, and a crease that shows when you tilt the card under a lamp drops it several grades at once. Ask for photos of the back in good light before you accept a seller’s NM or LP grade. Fakes give themselves away under a magnifier: real printing shows a fine, regular dot pattern, copies look blurred, and their backs often print too dark or too purple. Sealed product has its own tricks. Some people weigh packs, keep the heavy ones that hold the rare card and sell the light ones on. A modern English Pokémon booster box comes in film printed with small Poké Ball logos, so a box in plain film, or with tape under the wrap, has probably been opened. For a slab, look up the certification number on the grading company’s own website and check that the card and grade match.

Listing a binder, a deck or one chase card:

list valuable singles one at a time with the game, the set, the card number, the language and an honest condition grade, and photograph front and back on a plain surface so the edges show, plus the certification number on a slab. Sell a complete deck as a deck, since a player pays for not hunting down the pieces, and bulk commons as one lot with a count, because singly they are worth very little. If the collection came out of a house along with old coins and banknotes, those do better listed under coins than bundled with the cards. A buyer coming in from San Ramón or Limón for an expensive card will want to see it out of its sleeve, and many prefer to meet at a game store on tournament night, where another player can confirm the card is real.
