Following the Civil War, paper currency was disputed as to whether it must be accepted as payment. In 1869, Hepburn v. Griswold found that Henry Griswold would not have to accept paper currency because it could not truly be "legal tender" and was unconstitutional as a legally enforceable means to pay debts. This led to the Legal Tender Cases in 1870, which overturned the previous ruling and established the paper currency as constitutional and proper legal tender that must be accepted in all situations.
