Gladiator's Assault - Booster Box [1st Edition]

Is a booster box of GLAS worth opening?

Box price$2,450TCGplayer market price
Expected value$235$234 to $238 depending on the rates
If you sell the cards$191With a 5% fee and leaving out cards under $0.50
A typical box$138The median of 10,000 simulated boxes
You get your money back0.0%Almost never

On average, no: selling the cards from a GLAS box would get you $191, 8% of the $2,450 it costs. A typical box gives $138 and only 0.0% 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).

GLAS 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.

2007-2010 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 and Ghost 1 in 288. The Secret Rare (often quoted as 1 in 31, unsourced) and Ultimate Rares have no published rate: they don't count.
