1935 G1935 G silver certificates were printed in two varieties:
- If it does not have the motto "In God We Trust" on the back, in circulated condition it's worth about $2.25-$3. A nice crisp uncirculated one is worth about $10.
- If it does have the motto, it's a bit less common - $4-$6 circulated, $18-20 uncirculated.
Despite its date, the "G" series letter indicates your bill was printed in the early 1960s. During that time it was the practice to change a series date only when a bill underwent a major redesign, as opposed to the current practice of changing dates when a new Treasury Secretary is appointed.
Silver certificates typically had blue seals and serial numbers. Other colors were used on some very old bills and on bills printed for use in threatened regions during WWII.
God We Trust
That motto was first added to $1 bills starting with the 1957 series and was phased in on other series and denominations over the next few years. The 1935 G series was printed during that transitional time which is why some do and some don't have the motto.
A bill's serial number is just a counter so including it in a question generally doesn't help to identify it or affect its value. There are collectors who will pay a premium for bills with low or patterned serial numbers; e.g.12345678 or 00000005.
The serial number is almost never a determining factor in a bill's value. Condition, year, series letter, and bank district are far more important.
There are 2 varieties of this bill. Those without the motto In God We Trust are worth about $2.25-$3.; those with the motto on the back are worth $4-$6 depending on condition.
