Sealed products

Every sealed product of this set with today's TCGplayer market price.

How these numbers are computed
  • Price: the TCGplayer market price (USD) of ONE printing. Never another printing or grade; unpriced stays unpriced.
  • Changes: latest price vs the same printing's price 1, 7, 30, 90 or 365 days earlier (±1 day). Both prices come from TCGplayer; a missing day is never guessed.
  • Rankings: both prices ≥ $2, latest price at most 3 days old, and moves beyond sanity caps (e.g. +200% in a day) held back for review.
  • Indexes: chain-linked, base 100 on the first tracked day. Each day's change is Σ today ÷ Σ yesterday over the printings priced on both days by the same source — new listings and source switches never move them.
  • Volatility: standard deviation of daily log price changes over 30 days (≥ 10 consecutive-day returns). Trend: least-squares slope of the log price over 30 days.
  • History started on September 29, 2025. Each window appears once both of its endpoints exist; until then it says when it will be available.
