1864 Gold Dollar. The 1864 gold dollar is one of the low mintage Civil War coins. The total mintage was delivered on two different days during the year, with the first 2,400 pieces delivered on February 24. Late in the year, on December 6, another 3,500 pieces were produced for circulation. The total mintage thus comes to the limited number of 5,900 circulation strikes. This is a smaller number than the previous year, but more pieces were apparently saved.
