What is the value of a 1935 silver certificate?
Even though your question doesn't include the denomination, the only silver certificates with that date are $1 bills. Please see the Related Question for more information.
Banks don't buy or sell collectible currency. Regardless of a bill's age or rarity, a bank is only allowed to give you face value so you would only get $1 for a 1935 silver certificate. That said, most average-condition 1935 $1 bills aren't worth much more than a dollar or two anyway.

You didn't include the bill's denomination but the only silver certificates with that date were $1 bills. However, they were actually printed as late as 1964 (!) so you need to check what letter, if any, is next to the date. Then please see the question "What is the value of a 1935 [letter] US 1 dollar silver certificate" for more-specific information.
Please check your bill again. All HAWAII-overprint bills were issued during WWII and had a 1935-A series date and letter. They were created to thwart use by the Japanese if the islands had been invaded. The 1935-F series was printed during the second Eisenhower administration which of course was well after WWII. There's more information at the question "What is the value of a 1935 US 1 dollar silver certificate with HAWAII on it?"
You need to describe what the flaw is in order for us to get a better understanding of what exact error (or damage) you have. Chances are, if its a common silver certificate and it is an error it will raise its value. However, if it was done after the note left the press it is considered to be damage and will negatively impact its value.
