Cashing in old savings bonds that either you purchased or were given to you as a gift could result in a windfall. For example, just one Series E savings bond with a $1,000 face value purchased in 1975 and fully matured in 2005, would be worth more than $5,000. To find these old savings bonds, you can either use the U.S. Treasury's online tool or send the Treasury a claim form to start a savings bond search.
Search Treasury Hunt
Go to TreasuryHunt.gov to search for old Series E bonds purchased in 1974 or later that have reached final maturity and are no longer earning interest.
Click the "Start Search" button near the bottom of the page.
Type in your Social Security number in the box provided and click "Search" to see if any savings bonds are found. If no bonds are found, repeat the search with the Social Security number of a person such as a parent, guardian or relative who may have purchased the savings bonds for you in their name.
Send a Claim Form
Go to TreasuryHunt.gov and click on the "Forms" section. Select "Savings Bond Forms" in the left column.
Click the PDF "fillable form" link next to the "Claim for Lost, Stolen or Destroyed United States Savings Bonds" form.
Fill out as much of the claim form as you can, such as approximate issue dates and value amounts. List your Social Security Number, your full name and address, as well as that of any person who purchased the savings bond for you and may be listed on the bond. Write "Unknown" for any information that you don't know. Indicate whether you want payment by check, direct deposit or substitute bonds. Print the form when finished.
Type a separate letter and explain any special or extenuating circumstances regarding the savings bonds you think you might have. Include any information in the letter that does not fit on the claim form.
Take the form to a bank, credit union or other financial institution and sign the form in the presence of a "certifying officer."
