What a Legendary Summit card is worth
The most valuable Legendary Summit on this list is Legendary Summit (Left) from Delta Reign at $0.47£0.35€0.42, and the 2 priced copies across 1 sets are worth $1£1€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.
Legendary Summit is printed in Japanese as well: 3 cards across 1 sets, the most valuable of them Legendary Summit [Set of 2] from Storm Emeralda at $0.41£0.30€0.36. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
If you are trying to identify which Legendary Summit 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: Delta Reign.
