Can you still get 1st Edition Pokemon cards?
Yes, they do. “First edition” refers to the first print run of a particular expansion. They are usually only available for a limited time after the set's release, and are then replaced with “unlimited” edition cards. Are you trying to ask if Pokemon still prints first edition runs of its trading card game?
How do I know what series my Pokemon cards are from?
To identify the set, look for a little symbol at the bottom of the card, next to the card number. There are a bunch of these set symbols… 5-6 sets are released every year, each with a different set symbol, and they've been printing cards since 1999!
What do 1st Edition Pokemon cards look like?
So to recap, 1st Edition came first; they hail from '99, have a little stamp below the featured Pokémon and lack the drop shadow that outlines the right-hand side of the character box. Shadowless came next, and are separated by 1st Edition only by the absence of the stamp saying so.
