What is the value of a 1934 A US 5 dollar bill with a yellow seal?

Answer 1

As of 03/2011 approximate prices are:

Circulated: $20 to $60 depending on the bill's condition

Uncirculated: $250

Your bill should have the words North Africa overprinted in large letters. It's an interesting artifact from WWII - the US printed special bills for use in combat zones and threatened areas such as Hawaii. They were overprinted with the places where they were to be used and had special colors to distinguish them from standard bills. That way they could be quickly declared worthless if they fell into enemy hands.

Serial Numbers

A bill's serial number is a counter and a security feature. In most cases it doesn't affect a bill's value or help to identify it. Some collectors specialize in bills with low serial numbers (e.g. 00000005) or unusual patterns (12344321) so these can bring above-average prices.

DISCLAIMER: The values quoted are market averages as of the date shown, but may be different for an individual bill due to variations in quality and other factors. Also the wholesale (buying) price of a bill will be less than the selling (retail) price. A reputable currency dealer will be able to give a more accurate valuation based on an in-person inspection.
