Secrets of Eternity Booster Box [1st Edition]

Is a booster box of SECE worth opening?

Box price$40.15Cardmarket, converted to dollars
Expected value$57.80$57.40 to $59.00 depending on the rates
If you sell the cards$16.80With a 5% fee and leaving out cards under $0.50
A typical box$14.80The median of 10,000 simulated boxes
You get your money back2.8%In 1 out of 36 boxes

On average, no: selling the cards from a SECE box would get you $16.80, 42% of the $40.15 it costs. A typical box gives $14.80 and only 2.8% 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: good (several sources that agree).

SECE 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.

2010-2015 core booster: 8 commons and 1 rare per pack, with a foil in some packs. Konami ratios: Super 1 in 5 packs, Ultra 1 in 12, Secret 1 in 23 and Ghost 1 in 288. Ultimate Rares have no published rate: they don't count.
