There were a lot of silver certificates printed in the last years of this note's issuance, so unless it's uncirculated and not creased, it's probably not worth more than $1.50 or $2.00 retail.
The U.S. never issued an F series 1957 silver certificate. The last series letter was B. In any case the last runs of silver certificates were widely saved so they do not have a high collectible value. Circulated 1957, 57-A and 57-B bills retail for at most $1.50 if worn, maybe twice that if crisp and unfolded.
a mint condition silver certificate is worth $5-$6.
It is worth caca
These are very common among collectors and retail for only about 25 to 50 cents above face value.
The US only issued $1 silver certificates dated 1957. No other denominations have that date. The last $20 silver certificates were issued in the 1891 series.
These were saved in great numbers and retail for about $1.25. Note that ALL 1957 silver certificates have the motto on them, as required by a 1955 act of Congress.
All silver certificates printed from 1928 to 1957 had blue seals. Please see the question "What is the value of a 1957 A US 1 dollar silver certificate?" for more information.
There is no series C for 1957 silver certificates, only A and B. You may be looking at part of the serial number and not the print series letter which is next to the date. In any case 1957 silver certificates are very common among collectors and sell for about $1.25 - $1.50
I wood like to no what there worth, I have two 1957
If you mean a series 1957 silver certificate 1 dollar bill value may be $5.00 but only if it's a crisp uncirculated note with no folds, it's got to look like a new bill
Please check your bill again and post a new, separate question. "B" is the highest series letter for 1957 $1 bills.
Please check again and post a new question. No $2 bills were printed with the 1957 series date, and the last $2 silver certificates were dated 1899.
