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.

And if you sold the cards?

$273.90 is what the cards are worth to a buyer. It is not what you would be paid for them.

Cards worth more by the thousand than listed

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 30% 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.

Questions people ask

It's the average value of the cards in a box. Imagine opening a thousand boxes of this set and adding up every card at its market price — divide by a thousand and you get $273.90. It is not what your box will be worth. Most boxes come in lower, because a small number of very expensive cards drag the average up.
