I have no clue about paper currencies. What are these things valued at? I would hope more than 50 bucks! I bought all three for $70.
The 10 says first national bank of Grafton with an S mint I believe?
I don't know a whole lot about paper money but I would venture to say if you spent $70 you did pretty well.. I would have paid $70 for them.. Nice finds
The bottom two are Federal Reserve Notes, series of 1914 (as noted above) printed in Cleveland and signed by White and Mellon. There are two types of this bill (sorry, I don't know the difference) but I can tell you that catalog retail values for that bill , by type, were $90 and $115 in 2008; and $160 and $225 in 2010--in very fine condition. Though yours do not come up to that level of condition, these values still show that you made a great buy. Congrats.
