Quagsire cards.

What a Quagsire card is worth

The most valuable Quagsire on this list is Quagsire from Aquapolis at $93.03, and the 16 priced copies across 16 sets are worth $402 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 Quagsire 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: Aquapolis, EX Team Rocket Returns, EX Unseen Forces.
