By 1870 the United Stated managed to piece itself back together once Georgia joined the Union thus dissolving the Confederated United States once and for all. Additionally, the 1870 census reported a 22.6% population increase over the 1860 census results. It’s quite possible the reason for this increase is due to the newly freed African Americans, who were once counted as 3/5 a person and were now counted as a one person after the 14th amendment was ratified in 1868.
Despite limited coinage circulation fro 1863-1874, these nickel three-cent coins, the first nickel coins ever allowed in circulation, passed through legislation at the end of the Civil War. By 1870 these coins were virtually useless and usually thought of as more of a pain; yet they somehow stuck around until 1889, when the denomination was eliminated entirely.
