What is the value of a 1934 A US 500 dollar bill produced in Richmond VA?

It was printed in Washington. Richmond is the Federal Reserve District that ordered the bill and distributed it. There's more information at the Related Question.

Until 1990 all US banknotes were printed in Washington. That year, a second facility was opened in Fort Worth. Each Federal Reserve district requests a print run of denominations needed in its jurisdiction, and the Bureau of Engraving and Printing prints bills with that district's letter (and before 1990, its city name).
