What a Mist Energy card is worth
The most valuable Mist Energy on this list is Mist Energy (Cosmos Holo) from Prize Pack Series Cards at $3.85£2.90€3.39, and the 3 priced copies across 2 sets are worth $7£6€7 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.
Mist Energy is printed in Japanese as well: 4 cards across 2 sets, the most valuable of them Mist Energy (Master Ball Pattern) from Terastal Fest ex at $1.94£1.46€1.71. 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 Mist 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: Prize Pack Series Cards, Temporal Forces.
