Ok , theres from 1946 to 1964 with D and S mints most but not all years , unless they are mint condition its a buck apiece with the exceptions of the 1949S 1950S ,1949 maybe a buck or two extra being the key dates of note.
Beware.... I went on ebay some people say complete silver Roosevelt...what you get is a nice looking case that says the complete silver Roosevelt...(3 coins mounted 1-p, 1-d and 1-s).
I have priced complete silver Roosevelts....they go from 70$ to 200 depending on Fair to BU condition.
