As of 2015, 1957 $1 silver certificates in average circulated condition are typically valued at roughly $1.50. Bills containing a star note at the beginning of the serial number sometimes command up to $3.00 each from some enthusiasts.
Sometimes collectors are willing to pay up to $10.00 each for a run of consecutive, uncirculated 1957 star note certificates.
The 1957, 1957A, and 1957B series blue seal certificates are equally common, with none commanding a premium over the others. Since the bills were produced by the millions and are still extremely common today, they are not highly sought after by collectors.
