How much is a 1981 25.00 savings bond worth?

The value of a 1981 $25 savings bond depends on its type (Series E or Series I) and whether it has matured. A Series E bond issued in 1981 typically matures after 30 years, so if it hasn't matured yet, it might be worth around $75 to $100 if redeemed now, depending on interest rates and inflation. However, if it has matured, it can be worth its face value of $25 plus interest accrued. For the most accurate value, it's best to check with the U.S. Treasury or use their online savings bond calculator.
