Right now: the best rip in Quarter Century Bonanza is the Booster Pack at $9.49 against $10.67 of expected pulls — a −4% margin after ~15% selling fees, and a 22% chance it actually pays for itself. Figures refresh every two hours.
Quarter Century Bonanza (RA03) is an all-foil Yu-Gi-Oh! Rarity Collection released November 8, 2024: five cards per pack, every card Super Rare or better, 24 packs per box. It packages well-known cards in Quarter Century Secret, Platinum Secret, Prismatic Collector's and Prismatic Ultimate finishes, so the priced list runs to nearly a thousand variants and the sealed market treats it as a collector's product.
There is no dead slot: each of the five cards rolls independently, Super Rare about 55%, Ultra 27%, Secret 12%, Collector's Rare 3%, Quarter Century Secret 2.5%, Prismatic Ultimate or Platinum 0.4% and Starlight 0.1%. Across five slots that means a Quarter Century Secret in roughly one pack in eight. Blue-Eyes White Dragon, Dark Magician Girl and Black Luster Soldier - Envoy of the Beginning are the chase.
Products are loose packs and the 24-pack booster box. Because every card is a foil, pack EV is unusually stable for Yu-Gi-Oh!, and the question is simply whether sealed prices have run ahead of it. Pull rates are community estimates; Konami publishes none. The live table below shows the fee-adjusted picture for both products and updates every couple of hours.
