My wife's sister traded me this yesterday for a regular newer $50. I'm not sure if it's worth anything over face or I should just spend it as it's got some pinholes, fold tear, wear, etc and I don't know enough about paper money to determine for myself. I used http://www.mycurrencycollection.com/reference/star-notes/lookup and it seems middle of the road as seen in screen cap below.
Personally, I'd keep it, if I had the $50 to spare. At the very least, you'll have squirreled away fifty bucks.
I'd probably hang on to it if you could afford to do so. It's a neat example of an old style $50, it's a star note and it's from a fairly small run. It's a bit rough...but if it were me, I'd hang on to it. If you ever really need it, you could always spend it later.
If you collect from circulation, this is a great find....a keeper. If you are a $50 star note collector, you would probably pass, even as a hole filler. Respectfully, when I opened the thread and saw the note, my eyes were first drawn to the missing corner and tear starting at the center top. Personally I would spend it or offer it at face to a collector that wanted it.
Keep it , the note is from 60's , somewhat rare star ... onething I noticed but I'm not sure ... is the lower left serial * , filled with ink ?? You see the normal star is hallow , it appears to me one of the two stars is a solid star ... if that's ture then add 200 dollars or so to the value ... that's an error, but I cannot be sure from the pic
