That’s not a nine, but a 1. One hundred riels. One dollar is worth about four thousand riel at press time, so this note is worth about 2.5 cents. I’m doing that in my head. If I’m wrong, report me to the Cambodian Currency Slander Guild. 

Note how the sun shines through a crack in the ancient temple: nice work. They didn’t have to do that, but it adds something.
