As the Treasury Department ponders which American woman should be featured on the $10 bill, an abundance of ideas is delaying the decision until next year.

The department is taking additional time to consider a range of options after receiving more suggestions than originally expected, the Treasury said Friday in an e-mailed statement. Secretary Jacob Lew is now expected to announce the choice in 2016.

Lew previously said in July that he would announce the new face of the redesigned $10 bills "in the very near future." The new $10 will be unveiled in 2020, according to a Treasury fact page, the 100th anniversary of the passage of the 19th Amendment, which gave women the right to vote.
