About this printing

As of Nov 11, 2026, a 1st Edition Brock's Onix 21/132 from Gym Heroes sells for about $17.60 ungraded, the median of its 28 sales in the last 90 days, and $85.00 in PSA 9 (3 sales in the last 12 months). That is 1.8× the Unlimited print at $9.97.

A 1st Edition card has the black “Edition 1” stamp just below the bottom-left corner of the artwork. Unlimited copies have no stamp. The ungraded price mixes conditions (copies listed as played are left out), because 1st Edition copies rarely sell often enough to split them; the recent sales below show what each copy was listed as.

Brock's Onix is card 21 in the Gym Heroes price guide. See every Onix card with prices.

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 $17.60, after the PSA fee for what the slab is worth (a 9 goes in at Standard, $59.99), $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 308 copies; 53 got a 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 11, 2026.
