Collecting United States currency is as much about history as it is art. Some of the early banknotes were beautiful works of art. The “Educational Series,” series of 1896 silver certificates were gorgeous. The famous Black Eagle from the 1890s was another beautiful banknote. Some people will add these to their collection strictly for display only. Great conversation starters and wonderful to look at. Then there the banknotes from the early American colonies that were denominated in pounds, shillings, and pence. And the controversial confederate currency is another great collection to have.
