>>86167362The term “greenback” as a colloquial term for paper money dates to the American Civil War, so people would certainly be familiar with it. Also, political movements on the frontier generally preferred paper money due to the lack of specie available locally and because inflation benefits those who owe a lot of money, but don’t have fixed wages, like farmers. Gilded Age/Progressive Era populists generally supported more paper money before switching to the more politically palatable Free Silver movement for this reason. For an antebellum example, it’s also why western states initially supported Jackson against the national bank, only to switch sides after he tried discouraging paper money in favor of gold and silver.
For movie examples, the Confederate money in For A Few Dollars More is specified to be in gold due to the hyperinflation in Confederate paper money.
