What a Marill card is worth
The most valuable Marill on this list is Marill from Southern Islands at $164.67£123.94€145.02, and the 29 priced copies across 24 sets are worth $459£345€404 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.
Marill is printed in Japanese as well: 31 cards across 29 sets, the most valuable of them Marill from Intro Pack Neo (Totodile) at $299£225.04€263.32. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
The highest PSA 10 on record for Marill sold for $25,393£19,112€22,363. 1st Edition and reverse holo printings are priced separately from the standard card, because they do not trade at the same money. Rarities here include Illustration Rare.
If you are trying to identify which Marill 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.
