I don’t think every Skwovet card is going to become super expensive or anything, but I still feel they’re worth keeping. I checked How much is a Skwovet pokemon card a while back and noticed collectors still care a lot about cards that are in really clean condition, especially from certain sets. Card prices keep changing depending on trends and nostalgia, so you never really know what might become popular later. But honestly, not every card needs huge value to matter. I still have a few old cards that probably aren’t worth much, but they remind me of different stages of my life and old Pokémon memories.
