2008 Topps K-Mart Rookie Card Variations

I stumbled upon these six cards on eBay. Initially I was a little baffled as to what they were. I had no idea gold bordered rookie variations existed. A quick Google search led me to one of my favorite blogs, bdj610's Topps Baseball Card Blog. I learned that they are part of a thirty card set that were exclusively offered through K-Mart blasters. Pretty cool.
