About this printing
As of Sep 27, 2026, a 1st Edition Onix 56/102 from Base Set sells for about $20.24 ungraded, the median of its 12 sales in the last 90 days, and $753 in PSA 10 (4 sales in the last 90 days). That is 10× the Unlimited print at $1.99.
A 1st Edition card has the black “Edition 1” stamp just below the bottom-left corner of the artwork. Every 1st Edition Base Set card is also shadowless. 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.
Onix is card 56 in the Base Set price guide. The Shadowless print sells for about $2.50 ungraded. See every Onix card with prices.
