$1.47£1.11€1.31 of the average is commons and uncommons at a few cents each, priced at what the market quotes rather than what a person gets for a box of them, so read the average as a ceiling. Only the packs are counted: any promo card packed alongside them is not. Rates from the published per-set openings read on Aug 30, 2026. Every product ranked, and how this is worked out.
