The American dollar may be among  the world’s strongest currencies, but when it comes to the look and feel of U.S. greenbacks, they're pretty boring.

Ask any world traveler, and you'll hear complaints about how the bills -- which are the same size, color and embossed with males faces --are hard to distinguish. 

But now that's about to change. 

The Treasury is expected to announce a redesigned $10 bill that will feature a woman on U.S. paper currency--the first time in more than a century.

From 1865 to 1869, Pocohantas was featured on a $20 note and today you can find women’s rights advocate Susan B. Anthony and Sacagawea on dollar coins.

It's still unclear who's face will adorn the $10 note.  Abolitionist Harriet Tubman won the top vote in a poll conducted by grassroots organization Women on 20s, which has been pushing for a female face over Andrew Jackson on the bill.

But many other countries around the world have featured women on their currencies for years. From leaders to influential cultural icons and of course royalty, the bills of another nations are pretty diverse, not to mention the array of colors and sizes.
