America’s banknotes once included the fascinating Silver Certificates featuring a blue Treasury seal and serial numbers. Each $1 Silver Certificate was backed by $1 in real silver at the U.S. Treasury! The final two series of $1 Silver Certificates were dated 1935 and 1957 … and now, you can own both of these historic banknotes. The Series of 1935 was America’s last bank note without the motto “In God We Trust,” while the Series of 1957 was the first series with the motto. They haven’t been seen in circulation for almost 50 years, so this is a rare opportunity to own both notes in a matching set!
