Electric Generator cards.

What a Electric Generator card is worth

The most valuable Electric Generator on this list is Electric Generator (Cosmos Holo) from Prize Pack Series Cards at $0.34, and the 5 priced copies across 4 sets are worth $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.

If you are trying to identify which Electric Generator 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: Prize Pack Series Cards, World Championship Decks, Scarlet & Violet Base Set.
