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.
- Floor (10%)
- $170
- Typical
- $271
- Average (EV)
- $320
- Lucky (90%)
- $482
The average box ($320) is $49.55 above a typical box ($271) — 15%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.
- Box price
- $577
- Standalone pack listing
- $58.65
- Implied pack (box / packs)
- $48.08
- EV per pack
- $26.70
- $320 / box
- Return opening box
- −44%
- Return buying packs at listing
- −54%
The box is the better deal per pack ($48.08 vs $58.65 listing). Still a losing bet on average at −44% return.

- P(box ≥ expected value)
- 33.2%
- Typical box (median)
- $271
- Average box (EV)
- $322
- Unlucky box (10th pct)
- $170
- Lucky box (90th pct)
- $482
- God box (99th pct)
- $1,412

Where a box's value comes from
Expected contribution of each booster slot to the $320 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.
Top cards driving box EV
Individual card contributions to the $320 expected box value (pull rate times current price).
