In 1868, Andrew Johnson became the first sitting US president to be impeached by the House of Representatives after he ignored the Tenure of Office Act. The act required the president to go through the Senate before he could dismiss an important office member. Shortly after the act passed, Johnson dismissed the Secretary of War without going through the Senate and was impeached by the House of Representatives by a vote of 126 to 47. The vote for impeachment was then passed to the Senate where Johnson escaped removal from office by just one vote. This 1868 double eagle was minted during this intriguing political incident.
The ease with which blood flowed during the Civil War led to a religious revival in the United States that found its expression in coinage with the addition of the motto IN GOD WE TRUST to many denominations. In the case of the Double Eagle, the Mint made this addition quite easily in 1866 by placing the wording within the oval of stars above the eagle's head on the reverse. The Type II design, as it has since become known, remained in production through 1876, after which it was further modified by changing the appearance of the reverse denomination from TWENTY D. to TWENTY DOLLARS. This type is rightly recognized as the most conditionally challenging in the entire Liberty Double Eagle series, and Mint State survivors of all issues are scarce from a market availability standpoint, if not downright rare in an absolute sense.
