1. 1998 Japanese Promo Card – HOLO – Illustrator Pikachu – PSA 7 NRMT

As you’ve noticed, many of the cards that fetch the biggest prices online aren’t traditional Pokémon cards. Instead odd promo cards, like this Illustrator Pokémon card, tend to demand big money. According to PWCC, only about 40 of these cards were ever made and released. They were given out during three art competitions held in Japan where contestants were asked to create their own Pokémon cards. Winners received custom printed cards featuring their original artwork as well as this rare Illustrator Pikachu card as a trophy. This card highlights an exclusive piece of artwork created by Atsuko Nishida, the original character designer of Pikachu. As a result, whenever this rare card goes up for sale it brings in huge amounts of money.
