This is an average. A few very expensive cards pull it upward, so most individual boxes land below it. Opening one box is closer to a lottery ticket than an investment — the number below tells you whether the lottery is priced fairly.
$206.64 is what the cards are worth to a buyer. It is not what you would be paid for them.

Two things separate the two figures. Fees take 10.75% commission plus 2.5% and $0.30 on every order, and postage on a single card runs about $1.10 — a bite a cheap card cannot absorb. And 43% of the box's value sits in cards below roughly $1.66, the point where a card is worth more thrown into a bulk lot at $0.04 a rare than listed, packed and posted. Selling the whole box to a buylist in one go pays less again.
Assumes one card per order, which is the cautious reading — a buyer taking several cards at once splits the fixed costs between them. Fees are TCGplayer Marketplace rates as of February 2026; bulk rates are current cash buylist.
We start from what a box costs right now. Put in the price you're actually being asked to pay and the answer updates.

The cards are worth more than the box
At $165 a box you'd come out about $41.25 ahead on average. Over many boxes that edge is real — but any single box can still be a dud.
