Why should we fight to put a politician on our currency? Aren't their others worthy of that honor?

Soooo, let me get this straight, (and I'm NOT trying to antagonize you, just asking), ...you think the man that led us through the revolution, then helped to frame the new country and even refused the crown when it was offered to him shouldn't be on the $1 Dollar bill? Or the man that literally saved the union, freed the slaves and placed the South onto the path of reconstruction rather than subjugation after the Civil War shouldn't be on the $5 Dollar bill? I'm not sure I think Ronald Reagan should be on the $50 Dollar bill (always thought Grant's contribution during the Civil War gave him that honor). If you want to honor people like Thomas Edison, Booker T. Washington, Martin Luther King and Jane Addams, ...wouldn't it be better to put them on coins that can be struck in a commemorative fashion making them worth more? Just asking.
