Here's one I hadn't seen until just recently. This is a 2010 Sportkings National Sports Collector's Convention Ernie Banks Jersey Promo. I believe there are two versions of this card, a silver version with a stated print run of 9, and a gold version which is a 1/1. Sportkings typically issues a promo set of game used cards at the National Sports Collector's Convention each year. The last couple of years, these cards have been very limited, so it is a little hard to know exactly what is out there. There is also an Andre Dawson from this same 2010 set that I have known about since right after the cards were issued. But this one is new to my master checklist, and it's always fun to run across something new!
