How much is a1935 one dollar bill worth with blue seal
About $1.25
There's no such thing as a "blue silver dollar". If you're referring to a blue-seal silver certificate (a paper bill and not a coin) please post a new question with the bill's date and what letter if any is next to the date.
A 20-dollar bill with a blue seal indicates that it is a Federal Reserve Note, which is the standard currency issued by the U.S. government. The blue seal represents the Federal Reserve Bank that issued the bill. Regardless of the seal's color, a 20-dollar bill is worth its face value of $20. However, if it is an older or rare version, its collector's value could be higher.
Please post a new question with the bill's date. If there is a small letter under the date, include that in your posting.
Between $10 and $100 dollars depending on your buyer/bidder.
