https://en.wikipedia.org/wiki/Nickel_(United_States_coin)
A nickel, in American usage, is a five-cent coin struck by the United States Mint. Composed of 75% copper and 25% nickel, the piece has been issued since 1866. Its diameter is .835 inches (21.21 mm) and its thickness is .077 inches (1.95 mm). Due to inflation, the purchasing power of the nickel continues to drop and currently the coin represents less than 1% of the federal hourly minimum wage. In 2015, over 1.5 billion nickels were produced at the Philadelphia and Denver mints.
The silver half dime, equal to five cents, had been issued since the 1790s. The American Civil War caused economic hardship, driving gold and silver from circulation; in response, in place of low-value coins, the government at first issued paper currency. In 1865, Congress abolished the five-cent fractional currency note after Spencer M. Clark, head of the Currency Bureau (today the Bureau of Engraving and Printing), placed his own portrait on the denomination. After the successful introduction of two-cent and three-cent pieces without precious metal, Congress also authorized a five-cent piece consisting of base metal; the Mint began striking this version in 1866.
The initial design of the Shield nickel was struck from 1866 until 1883, then was replaced by the Liberty Head nickel. The Buffalo nickel was introduced in 1913 as part of a drive to increase the beauty of American coinage; in 1938, the Jefferson nickel followed. In 2004 and 2005, special designs in honor of the bicentennial of the Lewis and Clark Expedition were issued.

https://en.wikipedia.org/wiki/Impeachment_of_Andrew_Johnson
Andrew Johnson, the 17th President of the United States, was impeached on February 24, 1868, when the United States House of Representatives resolved to impeach the President, adopting eleven articles of impeachment detailing his "high crimes and misdemeanors", in accordance with Article Two of the United States Constitution. The House's primary charge against Johnson was violation of the Tenure of Office Act, passed by the U.S. Congress in March 1867, over the President's veto. Specifically, he had removed from office Edwin McMasters Stanton, the Secretary of War—whom the Act was largely designed to protect—and attempted to replace him with Brevet Major General Lorenzo Thomas. (Earlier, while the Congress was not in session, Johnson had suspended Stanton and appointed General Ulysses S. Grant as Secretary of War ad interim.)
The House approved the articles of impeachment on March 2–3, 1868, and forwarded them to the Senate. The trial in the Senate began three days later, with Chief Justice Salmon P. Chase presiding. On May 16, the Senate failed to convict Johnson on one of the articles, with the 35–19 vote in favor of conviction falling short of the necessary two-thirds majority by a single vote. A ten-day recess was called before attempting to convict him on additional articles. The delay did not change the outcome, however, as on May 26, it failed to convict the President on two articles, both by the same margin; after which the trial was adjourned.
