What a Grubbin card is worth
The most valuable Grubbin on this list is Grubbin from McDonald's Promos 2017 at $3.72£2.80€3.28, and the 13 priced copies across 11 sets are worth $8£6€7 together. Most of that sits in a handful of printings: the older the set and the scarcer the print run, the wider the gap to the rest.
Grubbin is printed in Japanese as well: 10 cards across 10 sets, the most valuable of them Grubbin from Enhanced Expansion Pack Sun & Moon at $1.85£1.39€1.63. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
reverse holo printings are priced separately from the standard card, because they do not trade at the same money.
If you are trying to identify which Grubbin you have, the set name is printed on the card and the collector number sits in the bottom corner. Open the card here and the page carries every printing of it, the graded prices, and whether grading the copy is worth the fee. Sets to start with: McDonald's Promos 2017, SM - Unbroken Bonds, Fusion Strike.
