What would be the best way to get a quote to be on a country's currency?

I am assuming you would have to be a quote from someone who is dead, long dead, legendary, or have made a significant impact in the country/region. <br><br>Adolf Hitler could be a quote, but it would be a country who doesn't have a track record with quote and who doesn't have a track record with the variety of denominations. I'm thinking of a country that has a track record of quotes, and legendary quotes that have big meaning for the nation, in this case the United States. <br><br>So, what would it look like to have a quote on the variety of denominations of US currency or a currency of a country that celebrates legendary people and quotes from history or their national customs?
