The $10 is listed at $14 in VF condition. I would keep it until I got a better one.
the $5 is listed at $12 in XF and $22 in AU condition-which is what it looks like to me. I would keep it.
I would keep the best of the $1 and $2 until you get better ones, and spend the rest, although really unless they are in perfect condition they have no premium.
Of course I agree that the shinplaster is a keeper too.
