What the data says

Only 6 ungraded copies sold in the last 90 days, too few to check the value against.

Ungraded copies are cheap, but graded ones are not: a PSA 10 is valued at $100.

PSA has graded 729 copies, 556 of them PSA 10 (76%). That describes the copies sent in, not the chance a given card grades 10.

Every sale here was matched to this exact card: the right number, set, printing and language, one card per listing, raw kept apart from graded. Where a venue sells by card and gives no listing title to check, the row says the venue named the card. Listings we can’t be sure of are left out. A price marked ≤ is an asking price, not a confirmed sale. On an accepted best offer we show what the buyer paid, not the asking price; where that isn’t on record the asking price is shown as a ceiling and never counts towards the price. A sale marked unusual is far from that grade’s market price: it stays on the record, and is left out of this page’s latest-sale and comparison figures. Sales record updated Nov 8, 2026.

Each graded row counts only that grade's sales; the ungraded row counts every condition. Sales a month is the 90-day pace. Last sale is the latest verified sale, never an asking price. How we calculate the UltraBall Market Value
