What the numbers say about OP15
A sealed OP15 box trades around $253 against a $120 MSRP, so the market is asking 112% more than Bandai did. That premium is the set being out of print rather than anything about the cards inside it.
Opening one returns $175 on average against $253 to buy it, a shortfall of $78.54 per box. The gap is real but not extreme, and a single box swings far wider than the average suggests in both directions.
Nami (CS26-27 Regionals Season 2 Top 64) (OP15-108) is the most valuable card in OP15 at $2,201, on its own 31% of the set's entire card value. The fifteen most valuable cards hold 87% 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 29% 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.

Is OP15 worth ripping?
Our live pull-rate model prices the expected value of opening a OP15 booster box at $175 against a sealed market price of $253: an EV ratio of 69%. 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.
