The math behind every max-buy price
- Grade odds from the PSA population report. What share of graded copies came back a 10, a 9, an 8, or lower.
- A haircut on the 10s. People only submit their best copies, and you’re buying from listing photos, so we assume your copy gems less often than the pop report shows. For sets before 2017 the cut is much deeper: the copies graded in the last year gem at about a twentieth of the all-time rate.
- What the slab should sell for. The chance of each grade times what that grade sells for, from recent sales.
- Minus every cost. Grading fee for that value tier, shipping both ways, and eBay’s selling fee.
- Leave room for profit. The max-buy price still leaves a 25% return and at least $15 on the table.
Confidence
Each card shows how many PSA-graded copies its gem rate rests on: High is 500 or more, Medium 100–499, Low under 100. Low-confidence cards can swing a lot on a few results, so treat them as leads, not answers.
Where the data comes from
Card details, raw and graded market prices, and PSA population reports come from Scrydex and refresh daily. Live listings come from eBay. Grading fees are NoOffseason’s own PSA prices.
