Six of a kind with a pair

This is the highest rated bill I've ever found on the 'coolness index' (99.25%). It's amazing to me that someone didn't spot it sooner because of the condition. It's got center fold wear but ita decent other than that. I got it in change at a gas station. What do you guys think it's worth? What's the best place to sell it? Six 2's and a pair of 5's
