Does it mean it's one of the first ones ever printed or what.
1st Edition cards in the Pokémon Trading Card Game refer to those that are printed in the first print run of a particular set. 1st Edition cards are typically only available in booster packs for a limited period after the initial release of a particular Expansion, and are then replaced by an Unlimited Edition until the printing of that set ceases. http://bulbapedia.bulbagarden.net/wiki/1st_Edition_(TCG)
