It won't happen till 2030 or later, and by then paper money will be less used than today....Harriet Tubman will grace the $20, replacing Old Hickory, President Andrew Jackson.
At least the government didn't sell naming rights. Ms. Tubman led an impressive life and I understand change isn't easy, but President Jackson was a Democrat so getting rid of him will be OK in some quarters.
Just don't anyone be thinking replacing Ben Franklin on the C note.
