I recently purchase a small group of cards that contained one E121-80 card (that I needed for my collection) and tw0 E121-120 cards (which I don't collect and are shown below). As I was looking a bit closer today I noticed that the card stock on the E121-120 is much thinner that anything that I have in my E121-80 collection. Are all E121-120 cards on thinner stock? Do these look good?
