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.

Against selling raw at $0.30, 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.
