Just went with a friend to a couple of banks and bought $200 worth of $2 bills. (See Here). We did this to try to release $2's back into the wild and hopefully show some people that $2's are just regular notes. My classmates always think they go for a premium as high as $5 for say, a common 2013 series note, and I try to explain that that is simply untrue. The L's in separate stacks had consecutive serial #'s.
Buying all low end varieties of the $1 bill.
