Small size silver certificates were issued from 1928 to 1964, in denominations of $1, $5, and $10. Silver Certificates also known as Blue Seals and Blue Seal Notes are still legal tender but since 1968 they have been redeemable only in Federal Reserve Notes and may no longer be exchanged for silver. The Silver Certificate Currency Collection contains both the $1 and $5 note. The set is displayed in a protective vinyl portfolio. A Certificate of Authenticity is included.
