Judith Coplon, who was convicted...

...of espionage and conspiracy more than 60 years ago, died at age 88. Her convictions were later overturned:

In 1952, after winning the right to a new trial, she remained free on $40,000 bail. The bail money was not returned until 1967, when the Justice Department formally dropped the case.

$40,000 was a lot of money in those days. The article doesn't say whether or not Ms. Coplon was paid interest.
