Is a 1950 series C "pay to the bearer on demand" $20 bill worth anything above face value?

I also have a 1950 series "B" $10 bill with the same inscription. Both are not in mint condition but are intact. I also have a 1964 one dollar bill but it has a tear in it. I have several of the 1976 issue $2 bills. I'm just seeing if I have anything of worth to collectors.
