I’ve seen cards without rarity marks, but people keep telling me that those cards are from the base starter deck, but I know that is not true because I have an opened one and they definitely have rarity marks. My guess is that they might have come from the 1996 Base Gift Set, but that is only a guess. I’ve seen Jimmy sell a set of a bulbasaur, charmander, and squirtle before, but I can’t remember what the description was. I had a very badly used Bulbasaur once, but since it was in such bad condition I sold it. Maybe only Charmander, Squirtle, and Bulbasaur and their evolutions have no rarity marks. I haven’t seen a card other than them or their evolutions without a rarity mark before. Hopefully someone knows more about them.
Yeah i saw the link in the item description the same seller has a venasaur and a chansey up for sale as well and both have no rarity symbol.
