Back in 1997 and 1998, Japanese magazine CoroCoro Comics held several competitions for its artistically inclined readers to design their own Pokémon cards. The winners were rewarded with the Pokémon Illustrator card, of which only 39 were ever made, thus making it incredibly rare.
Over a decade ago one of these cards went for an impressive $23,000. However, another recently came up for auction in Beverly Hills, California where it sold for $54,000. Not surprisingly, this makes this set a record for being the most ever paid for a Pokémon card.
Considering this, I highly encourage everyone out there to double check their collections. Sure, these cards constituted only a fraction of a fraction of a percent of the millions of cards printed, but there’s no harm in looking.
