What a Popplio card is worth
The most valuable Popplio on this list is Popplio from Mega Evolution Promo at $5.32£4€4.69, and the 13 priced copies across 9 sets are worth $27£20€24 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.
Popplio is printed in Japanese as well: 4 cards across 4 sets, the most valuable of them Popplio from Enhanced Expansion Pack Sun & Moon at $5.03£3.79€4.43. 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 Popplio sold for $99.95£75.23€88.02. 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 Popplio 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: Mega Evolution Promo, McDonald's Promos 2017, Miscellaneous Cards & Products.
