@TechnoDestructo: On behalf of the Bureau, we wanted to thank you for your interest and comment about redeeming bonds that are no longer gaining interest.

Once the value of the bond has been determined by using our bond calculator: http://www.treasurydirect.gov, you can cash your bonds and savings notes at most local financial institutions. When you present the bond(s), you’ll be asked to establish your identity. You can do this by presenting a valid ID, such as a driver’s license, or being a customer with an active account open for at least 6 months at the financial institution that will be paying the bonds.
