What is the value of a silver certificate dollar bill series 1957 D 622?
The last $1 silver certificates were the “1957 B” series. I am guessing you are looking further to the right of series and picking up the position letter and plate number which are not part of the series. The would make the series of the bill simply “1957”. The value will depend upon the condition of the bill. If the condition is below “good” it is probably only worth $1.00. If the bill is in “good” it is worth about $2.00. If it is in the best condition possible it is worth about $15.00.
