What a Meltan card is worth
The most valuable Meltan on this list is Meltan (Stellar Crown Stamped) from Miscellaneous Cards & Products at $11.64£8.76€10.25, and the 11 priced copies across 9 sets are worth $24£18€21 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.
Meltan is printed in Japanese as well: 13 cards across 10 sets, the most valuable of them Meltan from V Starter Decks at $2.75£2.07€2.42. 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 Meltan sold for $75£56.45€66.05. 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 Meltan 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: Miscellaneous Cards & Products, Temporal Forces, SM Promos.
