Actually....there is a collector's market for private-lable credit cards that has been around for decades. Some of the original Sears charge cards (metal) can bring good $. With this being a cross-collectible, $50.00 is probably on the high end of the spectrum. Remember, people are more likely to destroy old credit cards rather then toss them in a drawer (like slot cards). IMO, they would be worth around $25/ea.
