Every Rattata card we price, most valuable first. Prices are what copies actually sold for, updated daily.
The same Pokemon is also printed as Alolan Rattata and Lt. Surge's Rattata, priced separately because the game treats them as different cards.
What a Rattata card is worth
The most valuable Rattata on this list is Rattata from Legendary Collection at $149.99£112.89€132.09, and the 21 priced copies across 20 sets are worth $540£406€475 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.
Rattata is printed in Japanese as well: 23 cards across 21 sets, the most valuable of them Rattata from Vending Machine cards Series 1 (Blue) at $33.54£25.24€29.54. 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 Rattata sold for $3,480£2,619€3,065. 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 Rattata 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: Legendary Collection, Rumble, EX Team Rocket Returns.
