What a Master Ball card is worth
The most valuable Master Ball on this list is Master Ball from EX Deoxys at $29.11£21.91€25.64, and the 7 priced copies across 7 sets are worth $94£71€83 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.
Master Ball is printed in Japanese as well: 11 cards across 11 sets, the most valuable of them Master Ball from Intro Pack Neo (Totodile) at $87.85£66.12€77.37. 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 Master Ball sold for $416.18£313.24€366.52. 1st Edition and reverse holo printings are priced separately from the standard card, because they do not trade at the same money.
