The $100 bill should be dedicated to American letters. I would start with Mark Twain.
The $50 bill should be dedicated to the American arts. I would start with George Gershwin.
The $20 bill should be dedicated to American science. I would start with Thomas Edison.
The $10 bill should be dedicated to the American military. I would start with George Patton.
The $5 bill should be dedicated to American women. I would start with Dolley Madison.
The $2 and $1 bills should be eliminated, using the Canadian example, and replaced with coins.
