What a Taillow card is worth
The most valuable Taillow on this list is Taillow from EX Delta Species at $26.50£19.95€23.34, and the 15 priced copies across 15 sets are worth $102£77€90 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.
Taillow is printed in Japanese as well: 12 cards across 11 sets, the most valuable of them Taillow from ADV Expansion Pack at $4.97£3.74€4.38. 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 Taillow sold for $868.16£653.42€764.56. 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 Taillow you have, the set name is printed on the card and the collector number sits in the bottom corner.
