How to Catalog a Magic: The Gathering Collection

The most common mistake is starting alphabetically at card one. You will burn hours on bulk commons worth a few cents each and quit before you reach anything that matters.

Instead, do a fast physical pass with three piles:

• Bulk: commons and uncommons you recognize as draft leftovers. Box them. You can catalog bulk later, or never.
• Playables: cards you actively use in decks. Set them aside so cataloging does not break your decks.
• Potential value: rares, mythics, foils, anything old, anything with unusual framing or a promo stamp. This pile gets cataloged first.

Speed matters more than precision here. If you hesitate on a card for more than two seconds, put it in the value pile and let the catalog sort it out later.

A card name is not a price. Sol Ring has been printed in Limited Edition Alpha and in dozens of Commander precons, and those copies differ in value by orders of magnitude. The same is true across the game: reprints, foils, borderless and extended-art treatments, promo stamps, and serialized cards can make two visually similar copies worth wildly different amounts.

Two details on the card itself pin down the printing:

• The set symbol, or on modern cards the three-letter set code in the bottom-left corner.
• The collector number, printed next to the set code. Special treatments usually have numbers beyond the main set range.

If your catalog only records card names, your collection value is a guess. Record the exact printing from the start, because going back to fix it later means handling every card twice.

The best sorting system is the one that matches how you use the collection.

• By set, then collector number: best for collectors who care about value and set completion. It mirrors how price databases are organized, so finding a specific copy is fast.
• By color, then name: best for deckbuilders. Slower for valuation, faster for "I need a black removal spell."
• Value threshold: money cards in binders or toploaders, everything else in boxes by set or color. Most large collections end up here.

Whatever you choose, sort after you catalog, not before. Cataloging an unsorted pile works fine when the tool identifies each card for you, and physical sorting goes faster once you know what everything is worth.

Manual entry is where cataloging projects die. Typing a name, picking the right set from a list, and choosing foil or nonfoil takes 20 to 30 seconds per card. At a thousand cards, that is a full weekend of data entry.

A scanner changes the math. Cube scans cards continuously, card after card without stopping, so a full binder gets cataloged in one sitting. It identifies the exact card and the exact printing, cross-checking each scan multiple ways, and prices come from live trading-card market data with Magic card data built on Scryfall.

To be fair to the alternatives: a spreadsheet or a search-based entry app works, and for a couple hundred cards it may be all you need. Scanning earns its keep when the pile is measured in boxes. Cube's free tier covers 150 cards with full value tracking, which is enough to catalog your money pile and decide if the approach fits.

A catalog that only shows current value tells you half the story. Recording what you paid (your cost basis) lets you see return over time and make sane decisions about what to sell, trade, or hold. For older acquisitions, an honest estimate beats a blank field.

A card catalog also decays. Prices move constantly, and every booster pack, trade, and sale changes what you own. Two habits keep it accurate:

• Catalog new cards the day they arrive, while the purchase price is fresh.
• Let the tool handle repricing. Cube refreshes prices continuously, so the number you see reflects the market, not the day you scanned.

One caveat: card prices go down as well as up, and nothing in this guide is financial advice. A good catalog does not guarantee returns. It just means your decisions rest on real numbers.
