About the reverse holo

A near-mint reverse holo Grumpig 20/100 from Crystal Guardians goes for about $12.63 ungraded, 14× the non-holo at $0.91. We have 3 sales on record where the listing said reverse holo, 2 of them in the last 90 days; they are listed further down.

On a reverse holo the artwork is flat and everything around it shines: the text box, the borders of the card body and the background all carry foil. Tilt the card under a light and the picture stays dull while the rest flashes.

Reverse holos are pulled from the same booster packs as the regular print, so the reverse holo Grumpig shares its number, 20/100, with the main Grumpig card. Check the finish before you price a copy: sellers who have one nearly always say so in the listing title.

The non-holo Grumpig is $0.91 near mint. Grumpig is card 20 in the Crystal Guardians price guide. See every Grumpig card with prices.

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. Listings we can’t be sure of are left out. 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 and isn’t counted either. Sales record updated Sep 28, 2026.
