Lend me a fiver

The United States Treasury has announced that it will put a woman on a redesigned $10 bill that will be introduced in 2020. As of today it has not been decided who she will be. As long ago as 1967, soon after the introduction of decimal currency, the first version of the
Australian $5 note featured a portrait of the 19th century English humanitarian, Caroline Chisholm (1808-1877).

Universal female suffrage was achieved in Australia in 1902, but not in the United States until 1920. This is a rare historical instance of Australia leading where the United States follows, rather than the other way around.
