Every Team Rocket's Diglett card we price, most valuable first. Prices are what copies actually sold for, updated daily.
The same Pokemon is also printed as Diglett and Alolan Diglett, priced separately because the game treats them as different cards.
What a Team Rocket's Diglett card is worth
The most valuable Team Rocket's Diglett on this list is Team Rocket's Diglett (Team Rocket) from Ascended Heroes at $0.27£0.20€0.24, and the 3 priced copies across 1 sets are worth $1£0€1 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.
Team Rocket's Diglett is printed in Japanese as well: 3 cards across 1 sets, the most valuable of them Team Rocket's Diglett (Energy Symbol Pattern) from High Class Pack: MEGA Dream ex at $1.02£0.77€0.90. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
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 Team Rocket's Diglett you have, the set name is printed on the card and the collector number sits in the bottom corner.
