value of 1934 silver certificate ten dollar bill?

Answer 1

To many factors play a role here :

Is it a star note ?

What is the condition ? (folds, tears, marks, fading, worn areas, etc... )

Bank mark ?

Some star notes I know of have gone for over $500.oo but you need to show it to a dealer for a more exact price after knowing what to info to provide.

Answer 2

Officially? Ten dollars.

You should be able to find a collector who is willing to pay more... honestly, eBay might be your best bet. Depending on the condition, you might be able to get over $100 for it.
