We found an old $100 savings bond (Series E) issued in 1956 to my husband. What is it worth?

$700 I assume this is a Korean war bond. You bought them in school bond drives to help with the war. & had all school year to pay for them. $25, $50, $100 or more in denomination. They gave you odd money back at the end of the school year. Then bought the bond from your savings for the year. 

These bonds stopped earning interest after they were about 25 or 30 years old: I don't really remember any longer. Generally your bank can tell you what they are worth, and they can deposit the proceeds (at no cost) into your savings or checking account.

For more information on what they are worth and how you can cash them in, see the following site:

I'd love to tell you that it is worth a couple of million dollars but, I don't know. Contact whoever issued the bond and ask them.

Between $745 and $800.

The exact amount depends on which month of 1956.

$747.16 if issued in January or February 1956.

$798.24 if issued in December 1956.

Go and ask at the bank.

This is approximate assuming issue 6/1956

Purchase price $75

Final maturity 6/1996

Interest $702.16

Value $777.16

I think it stopped paying interest after so many years.
