All look like spenders, the $50 Star would be worth holding on to if in better condition but The writing on the front would turn allot of people away the 1934C $50 looks like it would Grade no better then Fine but still would have to think about that one! the $1 Blue seal Being a 35A is a little rarer then the 57 Series which are only worth about $17-$20 in Choice C/U your,s looks VF probably in the $10-$12 range.
I think that they are spenders, but if you are able to, I'd hold onto them. The notes grade what mpcusa said, but they still have a slight premium to them. Some may be turned off by the writing on the star note, but you never know.
It's too bad about the writing on the 1950D Star.......I know a guy that may be able to...sorry,never mind.
I'd keep em all, if you are gonna put any back into circulation, post it on the open forum first and keep it in a collectors hands instead of the shredder.
On the older FRN's, unless they are specifically collectable grades or rare or something I only save them as "emergency" money in case I need quick cash for something like a coin purchase.
Hey! I just got a 1934C $50 today. Mine's a little higher serial number than yours though and I'm keeping it! Check out "New Acquisitions" to see mine.
