What is the value of a 1923 A US 1 dollar bill with a blue seal?

Answer 1

The blue seal indicates your bill is a silver certificate, a form of paper money issued until the early 1960s. However there were no 1923 A $1 silver certificates printed, only 1923. If that's what you have, as of 11/2014 approximate prices are:

Circulated: $6 to $35 depending on the bill's condition

Uncirculated: $60

FAQ-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.
