What is the value of a 1934 US 1 dollar silver certificate?

Answer 1

Values as of 05/2010 are $10.-$15. in circulated condition, and $60 or more for a nice uncirculated one.

Be careful to distinguish this bill from the much more common 1935 series. The 1934 series of $1 bills was a one-time issue that's seen far less often than the successor 1935 series that was printed continuously until the mid-1960s. Most 1935 $1 bills only sell in the range $1.50 to $7.00 depending on their condition and series letter.

Serial Numbers

A bill's serial number usually has no effect on its value. Date, series letter, and condition are what normally matter.

Trivia: The rather garish reverse-side design on these bills and their immediate predecessors led to them being nicknamed "funny back" bills.
