TIL: India has 0 rupee banknotes in circulation. They mimic the design and size of 50 rupee notes, except they're worth 0.

The banknotes are issued by a private organization as a response to the extremely high level of corruption in the country. When people are extorted, they hand over these banknotes as a sign that they have absolutely no intention of paying. Apparently, it actually works. Government officials stop trying to squeeze illegal money out of them.

Five other countries have followed the Indian example: Yemen, Ghana, Benin, Mexico, and Nepal. Looks like we should probably join in too (:
