Here's a couple Sidney Crosby cards I picked up as a pair. From 2013-14 Dominion, I was able to get my hands on TWO mammoth jersey cards, but although they are similar, they still are just slightly different. One of them is the Prime parallel, numbered 16/25, which contains a two-colored swatch, right at the seam connecting gold fabric to black fabric. The other one is the base version of this card, which contains a white swatch, and is numbered 44/50
These cards were listed as a pair, so I was hoping to get them for just slightly less than if I were to buy them individually, but as it worked out, I ended up getting them for the sum of the average price of these two cards anyway, but at least I didn't have to overpay. Still, I'm very glad to be adding these to my collection.
