What a Varoom card is worth

Varoom is printed in Japanese as well: 15 cards across 8 sets, the most valuable of them Varoom (Master Ball Pattern) from Terastal Fest ex at $2.14£1.61€1.88. 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 Varoom sold for $90.41£68.05€79.62. reverse holo printings are priced separately from the standard card, because they do not trade at the same money. Rarities here include Illustration Rare.
