About this printing
As of Nov 11, 2026, a 1st Edition Koga's Muk 26/132 from Gym Challenge sells for about $17.74 ungraded, the median of its 19 sales in the last 90 days, and $238 in PSA 10 (6 sales in the last 90 days). That is 1.5× the Unlimited print at $11.60.
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.
Koga's Muk is card 26 in the Gym Challenge price guide. See every Muk 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 $17.74, 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 366 copies; 132 got a 10.
