Odds & fairnessEV 99%

The odds are the product.

Every pack publishes its odds table before you buy. The expected value of every pack is 99% of its price; the remaining 1% funds the verifiable draw and the 95% sell‑back floor. Tables only change when slabs enter or leave the PSA Vault.

In this demo the draw runs in your browser against the same tables, from a small pool of 14 real slabs — so the demo EV per pack (shown below) drifts from 99%. Production pools are sized per tier to hit it.

How a draw works

When you open a pack, a random number is requested from a verifiable randomness source. The number selects a tier by the published odds, then a specific slab from that tier's pool. The request ID and result are recorded with the pull so anyone can check it.

How market value is set

From recent PSA‑graded sales of the same card and grade, refreshed continuously. The value shown at reveal is the value the 95% sell‑back is paid against — it doesn't move between reveal and tap.

What 99% EV means

Across many packs, the average market value of slabs delivered is 99% of the price paid. Any single pull can land well above or below that; the odds table tells you exactly how often.
