During the early American Civil War, the federal government first issued United States Notes (the first greenback notes), which were not redeemable in gold and silver coins but could be used to pay "all dues" to the federal government. Since land purchases and duties on imports were payable only in gold or the new Demand Notes, the Demand Notes were bought by importers and land speculators for about 97 cents on the gold dollar and never lost value. 1862 greenbacks (Legal Tender Notes) at first traded for 97 cents on the dollar but gained/lost value depending on fortunes of the Union army. The value of Legal Tender Greenbacks swung wildly but trading was from 85 to 33 cents on the gold dollar.
