OP10Royal Blood

A sealed OP10 box trades around $252 against a $120 MSRP, so the market is asking 111% more than Bandai did. That premium is the set being out of print rather than anything about the cards inside it.

Our model puts the expected value of opening one at $88.47, 65% below what the sealed box costs. Averaged over many boxes you hand over $164 per box for the experience of opening it. OP10 is a set to hold sealed rather than rip.

Trafalgar Law (Manga) (OP10-119) is the most valuable card in OP10 at $701, on its own 36% of the set's entire card value. The fifteen most valuable cards hold 88% of everything the set is worth, so the rest of the checklist contributes very little in value terms.

Broken down by what you actually pull, alternate-art cards account for 36% of a box's expected return, at about 2 per box. That is the line the set's economics rest on, and it is why box results feel streaky: miss it and the rest of the box does not come close to covering the cost.

Our live pull-rate model prices the expected value of opening a OP10 booster box at $88.47 against a sealed market price of $252: an EV ratio of 35%. Like almost every booster box, ripping is negative expected value: the sealed box is worth more than the average of what is inside it. Rip for the fun and the chase, hold for the value.
