What is the value of a 1902 US 10 dollar bill?

Answer 1

Assuming the bill is a National Currency Note with a blue seal, as of 04/2012 approximate prices are:

Circulated: $225 to $450 depending on the bill's condition

Uncirculated: $1000

Private banks also issued paper money at that time. If your bill is from a private bank please post a new, separate question.

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.
