Is a booster box worth opening?

For each set: the average value of the cards in one sealed booster box, worked out from the set's single-card prices and its pull rates, next to what the box costs sealed. Sorted by value against price (cards worth $1 or more). Prices checked .

No sets to show tonight.

Cards under $1 are bulk: they rarely sell one at a time, so the main number counts them as $0. The other column counts them at market price. Sets we have no citable pull rates for aren't listed.

Where the pull rates come from

Why there's no Yu-Gi-Oh! or One Piece here yet

• Yu-Gi-Oh!: Konami doesn't state how many Starlight Rares or Quarter Century Secret Rares a box holds, or the Super/Ultra/Secret split in current core and side sets, and it doesn't state packs per box. Those cards carry most of a box's value, so there's no honest average to show. Konami product pages (e.g. Chaos Origins) · Konami's last stated core-pack ratios (2015, before Rares were removed) · Rarity Collection 5 slot chart (paired rarities, splits not stated)
• One Piece: Bandai publishes no pull rates or box guarantees for English booster boxes (only PRB-02's 'at least one SR card or better' per pack), and the community counts we found are single cases with unverified numbers that disagree with each other.

How it works

For each rarity: the cards of that rarity you get in a box × the average TCGplayer market price of the set's own printings at that rarity (a Secret Rare's price is the Secret Rare printing in this set, not a cheaper reprint). Printings with no market price are left out of the average and counted on each set's page. The chance of pulling one card assumes every card of a rarity is equally likely. Official rates are what the publisher states. Community estimates come from people counting their openings, and real boxes vary a lot.

Prices change every day. This is an average over many boxes, not a promise about yours: one box can land far above or far below it. It is not financial advice.
