Every Lairon card we price, most valuable first. Prices are what copies actually sold for, updated daily.
The same Pokemon is also printed as Team Magma's Lairon, priced separately because the game treats them as different cards.
What a Lairon card is worth
The most valuable Lairon on this list is Lairon from EX Legend Maker at $42£31.61€36.99, and the 20 priced copies across 18 sets are worth $172£129€152 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.
Lairon is printed in Japanese as well: 18 cards across 17 sets, the most valuable of them Lairon from Bonds to the End of Time at $10£7.53€8.81. 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 Lairon sold for $1,150£865.54€1,013. 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 Lairon 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: EX Legend Maker, EX Crystal Guardians, EX Power Keepers.
