the $50 would be the only note i can see that would fetch any type of premium, at least for right now. The low serial $20 could years down the road, but its not low enough to gather serious interest now, and the condition also doesnt help. As for the star note and the almost repeater ... well, they are worth $1 each
the star could fetch a premium now to the right collector and will increase more as time passes.
