Is it worth it

The booster box costs $1,177. Every card in XY - Steam Siege bought as a single costs $473.10 for all 116, and half of them are under $0.59. The money is in a handful: 71% of the set’s value is in its ten dearest cards, starting with Gardevoir EX (Secret) at $107.59. A box is a bet on those ten, and how often they turn up is not something anyone publishes, so this page will not pretend to know it.

What comes out of it

Every XY - Steam Siege card, which is what is in this booster box, dearest first. The median card in the set has moved -28.8% over three years. See the full set list.

What this price is

$1,177 is the TCGplayer market price, the number copies are actually changing hands at rather than what any one shop is asking. It is the same source as the card prices everywhere else on the site, so a box and the cards inside it are measured the same way and can be compared directly.
