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 11, 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

Against selling raw at $7.61, after the PSA fee for what the slab is worth (a 10 goes in at Standard, $59.99; a 9 at the same level), $25.00 shipping and insurance, and eBay US selling fees, as the selling calculator works them out, with its usual $5 postage and $1 packing on each sale: the same sum as the selling calculator. Each grade is charged the fee level its own slab price needs, so the break-even price carries the fee for a slab at that price, not the PSA 10 fee. These are outcomes if the card gets each grade, not the chance that it will. PSA has graded 64 copies; 22 got a 10.

About

About this card

Mystery Plate β is card 134 of 144 in the Skyridge price guide, a set released in May 2003 during the Wizards of the Coast era. Its rarity is Uncommon. The artwork is by Hiromichi Sugiyama. In the checklist it sits after Mystery Plate α 133/144 and before Mystery Plate γ 135/144.

What the data says

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

PSA has graded 64 copies, 22 of them PSA 10 (34%). That describes the copies sent in, not the chance a given card grades 10.
