Clarification question: I was sorting through my 2021 Topps Heritage Clubhouse Collection cards (relic cards) yesterday. As I was going through them, I noticed I had duplicate cards of one player. As I looked to see which one I was going to keep for my set I noticed that one of the cards has a piece of jersey material and the other card has a piece of a bat...same player/same card number. (Not Low Number vs High Number) Would this be considered a variation? I know that some jersey material cards come in different colors, but until yesterday I was unaware that the relic cards for this set came with two different types of relics. Either way I am going to keep both of them, but I wanted to ask to see if this is considered a variation.
