Legacy of the Master Booster Box

Is a booster box of OP12 worth opening?

Box price$292TCGplayer market price
Expected value$167$111 to $226 depending on the rates
If you sell the cards$132With a 5% fee and leaving out cards under $0.50
A typical box$79.59The median of 10,000 simulated boxes
You get your money back5.0%In 1 out of 20 boxes

On average, no: selling the cards from a OP12 box would get you $132, 45% of the $292 it costs. A typical box gives $79.59 and only 5.0% of boxes get your money back. If you're after a specific card, buying it as a single is usually cheaper.

How reliable the rates are: fair (community estimate).

OP12 pull rates

How many cards of each rarity group come in a 24-pack box, how many packs it takes to pull one specific card of the group and how much the group adds to the box value.

Where the numbers come from

The expected value adds up, for each rarity group, the copies in a box times the average price of its cards (the English card, with its TCGplayer price or, if there isn't one, Cardmarket's converted). The simulation opens 10,000 boxes with the same rates.

Community estimate for English boxes; the gold/silver Teach SPs are split out, ~1 in 60 boxes between the two.
