I was looking through my collection and I noticed I have three promos with unstamped and stamped variations. They are:
2006 Silver Pikachu Victory Medal
113/PCG-P Battle Road Autumn 2005 Pikachu
130/PCG-P Battle Road Spring 2006 Touch Exchange!
I was wondering if anyone knows if there any other promo cards that have both variations since I am trying to make a master list of cards and collect all cards/variations of cards.
