What a Butterfree card is worth
The most valuable Butterfree on this list is Butterfree from Legendary Collection at $228.41£171.91€201.15, and the 24 priced copies across 20 sets are worth $657£495€579 together.

The highest PSA 10 on record for Butterfree sold for $25,750£19,381€22,677. 1st Edition and reverse holo printings are priced separately from the standard card, because they do not trade at the same money. Rarities here include Secret Rare.
