What a Rotom Dex card is worth

The most valuable Rotom Dex on this list is Rotom Dex (Secret) from SM Base Set at $6.34, and the 2 priced copies across 1 sets are worth $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.

If you are trying to identify which Rotom Dex 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: SM Base Set.
