No, not really, all were either given away, buried, dropped to the currents of a river or burned, I don't know why but I never kept them for a long time, the only memento I carry is Blastoise coin thing that I have in my wallet next to my ID, it's an empty gesture though, as I don't remember why I put it there, and it has no real meaning, it's sort of strange because I never was a fan of Pokémon, and when I played it I went for Charmander, so I don't know what it's sentimental value is supposed to be, I'm half tempted to just throw it away.
