If the 1973 printed in several million are either "good condition, fair," or "a bit frayed" then they're probably not worth putting them up for sale (the fees will gobble up your profits).
If the 1954 $1 are truly Devil's Faces with the prefix of D/F (or Y/N) and the signature combo of Beattie / Rasminsky- they could be worth $1000 but it is more likely they are modified and may be worth a little over face (depending on condition).
