The Expedition base set paved the way for the e-Card Series with cards that featured Dot-Code technology to be used in conjunction with the Nintendo e-Reader, which allowed players to access data, play mini-games and unlock special attacks.

To make room for the dot code technology, you'll notice the card's left and bottom borders are wider than usual.

Interestingly, before the final product release, The Pokémon Company distributed these "For Position Only" cards to employees as a test run that should have never seen the light of day in the mainstream hobby.

However, it is believed that one of those employees had kept some of the original packs in which these cards were inserted and began selling them to hobbyists several years later.

The "For Position Only" test run included eight different cards, one of them being Charizard.

Nobody knows for sure how many were printed originally nor how many survive in circulation today, making this oddball card a cherished piece for any serious collector.
