What are series ee bonds worth?

Series EE bonds are U.S. government savings bonds that are sold at face value and earn interest over time. The interest rate is fixed and is typically compounded semiannually. After 20 years, they reach maturity and can be redeemed for their full face value, which may be significantly higher than the initial purchase price, depending on the interest accrued. Additionally, they can earn interest for up to 30 years before they must be cashed in.
