Every Magneton card we price, most valuable first. Prices are what copies actually sold for, updated daily.
The same Pokemon is also printed as Holon's Magneton and Dark Magneton, priced separately because the game treats them as different cards.
What a Magneton card is worth
The most valuable Magneton on this list is Magneton from Base Set (Shadowless) at $407.50£306.70€358.87, and the 50 priced copies across 36 sets are worth $1.8k£1.3k€1.6k 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.
Magneton is printed in Japanese as well: 48 cards across 35 sets, the most valuable of them Magneton from Mysterious Mountains at $199.99£150.52€176.13. 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 Magneton sold for $10,455£7,869€9,207. 1st Edition and 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 Magneton 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: Base Set (Shadowless), Legendary Collection, Skyridge.
