1957 $1 Star Note

That would depend on the condition of the note. If uncirculated, it would probably be worth at least what you paid and maybe more depending on how high of a grade it is. If average circulated, it would probably be worth only a few dollars more than what a avg. circ. no star $1 silver certificate is worth. I see those avg. circ. no star $1 silver certs. selling for about $2 each. If you post a pic would can give you a better answer.
