I do not think Donald Trump’s face will ever appear on US currency. First of all, there will not likely be new denominations of currency printed in the foreseeable future, and the faces on currency rarely change. If there are changes to currency there is a good chance that a women’s face would appear in the currency because there is already a campaign to make this happen.
Secondly, I do not believe Donald Trump will go down in history as a particularly good president. His policies thus far have been unpopular and his rhetoric makes him one of the most despised presidents of all time. In fact, he currently has some of the worst approval ratings ever reported.
