Togo
Nestor Yawovi Kogon is a Togolese teacher. When he is not instructing a class, he's collecting currency.
His curiosity for currencies has seen him rack up a collection of 1,200 coins and notes used in different countries and regions.
"It was especially after some students told me that they didn't know of a note that had just been retired that the idea of collecting notes really came to me", said Kogon.
Kogon wants to make his passion for old currency a public good.
He wants authorities to build a museum dedicated to Togo's economy, banking, and finance.
There, he says, his collection can be put on display for education and research purposes.
