What a Klang card is worth
The most valuable Klang on this list is Klang (Master Ball Pattern) from Black Bolt at $11.29£8.50€9.94, and the 15 priced copies across 12 sets are worth $30£22€26 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.
Klang is printed in Japanese as well: 12 cards across 8 sets, the most valuable of them Klang (Master Ball Pattern) from White Flare at $4.57£3.44€4.02. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
The highest PSA 10 on record for Klang sold for $91.38£68.78€80.48. reverse holo printings are priced separately from the standard card, because they do not trade at the same money. Rarities here include Illustration Rare.
If you are trying to identify which Klang 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: Black Bolt, McDonald's Promos 2012, Blister Exclusives.
