Toss-up$172 of cards inside, after selling costs

See the mathPrice history

Why it's a toss-up

The cards inside are worth $172 after selling costs. The box costs $135.

But 63 of 100 boxes lose money. A few big pulls carry the average.

Pull rates are still uncertain. The real value could be anywhere from $90 to $286. That's enough to change the verdict.

If you opened 100 boxes

  • 37 make money
  • 63 lose money

A typical box is worth $42. 1 in 10 boxes is worth $517 or more, and 1 in 10 is worth $17 or less.

The math, per box

From the price of every card to what you'd actually keep.

How we work this out

We price every card at its TCGplayer market value, take off the selling costs above, and open 100,000 virtual boxes slot by slot using the pull rates in the table. The verdict compares the cards with the box price and checks how often a box loses money.
