What you actually get

Most boxes land well below the average. Chase cards pull the mean up — your typical box is the median, not the EV.

The average box ($291) is $58.21 above a typical box ($232) — 20%of the EV comes from above-median outcomes you probably won't see.

Pack vs box economics

Should you buy a sealed box or individual packs? EV per pack is the same either way; the question is what you pay per pack.

Roughly 10% of boxes return more than the $475 you paid. You'd need to open about 28 boxes (~$13,300) for a 95% chance that even one of them breaks even. A typical box (median $232) is $58.21 below the $291 average - most of the EV lives in chase cards you probably won't pull.

Where a box's value comes from

Expected contribution of each booster slot to the $291 box EV. Cards valued under $0.25are treated as $0 bulk, since penny commons and foils can't realistically be sold at their listed price.
