What a Delta Rainbow Energy card is worth
The most valuable Delta Rainbow Energy on this list is Delta Rainbow Energy from EX Dragon Frontiers at $24.99£18.81€22.01, and the 3 priced copies across 3 sets are worth $53£40€47 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.
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 Delta Rainbow Energy 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: EX Dragon Frontiers, POP Series 5, EX Holon Phantoms.
