What is the value of an 1891 US 1 dollar bill?

Answer 1

Your bill should have a red seal and be either a silver certificate or a treasury note. As of 03/2015 approximate prices are:

Silver certificate -

Circulated: $150 to $500 depending on the bill's condition

Uncirculated: $850

Treasury Note -

Circulated: $125 to $300

Uncirculated: $550

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.
