have a woman on a new $25 bill instead of disturbing other bills.

We must have a woman on a dollar bill. So instead of disturbing other bills already in circulation, we should start a new bill specially with a woman on it. The best choice for this would be starting a new $25 bill circulation. This will not disturb the existing bills and at the same time start a new bill in circulation. Afterall, we have a 25 cent or a quarter coin which is probably the most used and useful coin that we have.
