Hey brother! I know of one card shop left in Knoxville. It is called Sports Treasures. It is at 4819 North Broadway Street, Knoxville, TN 37918. The guy (Eddie) has owned it since the late 80s and has tons of stuff ranging from cards to sculptures, to autographed memorabilia. He is a stickler on price but the other employees are easy to deal with. I stop by every time I visit. Best of luck.
