Also a kind reminder. We don’t need to lose our heads over something that boils down to interpretive semantics.
Simply put, if you have your own definition of what makes a rookie card a rookie card, there is accessible information for the populace to determine what that means for them.
If a rookie card means 1st Edition Base, then you get them.
If it means No Rarity, you get them.
If it means first appearance of a particular Pokemon, then you’ll get Magnemite 1st Edition Base for Magnemite. If it’s Marill, then you get the 1999 CoroCoro version.
If it means the first release of a particular set, then you get Pre-Release cards.
Otherwise, everything else boils down to factual information. If you want the first ever Pokemon TCG cards to be produced, then you get the Pikachu & Jigglypuff promos. If you want the first ever set, then you get No Rarity. And so on.
For many people here, the term probably means very little to us but it’s an interesting thing to discuss.
