The Base Set of Pokémon TCG cards first released on January 9, 1999 (USA; October 20, 1996, JPN), quickly gaining popularity following the hype of the game & anime series.
The earliest printed copies feature notable differences from unlimited versions, now commonly called "shadowless" cards, due to the lack of shadow effect around the art border. These cards can also be identified by the inclusion of both "99" & "©1999" in the copyright info.
This set featured 102 original cards: 69 Pokémon, 26 Trainers, and 7 Energy cards were pressed.
