Collecting all currencies in the world

Hey there! I'm Ivana from Croatia, 24 years old. I came up with idea of collecting a bill from each coutry/currency. Throught this collecting time I will meet a lot of people from all around the world and beside collecting my goal is to learn about other cultures and make friendships. Soon as I start collecting everything will be posted on social media (instagram and blog page I will create) as some sort of interesting educative content about each coutry, their culture and ofcourse their currencies.

For what i need money? When i find person who wants to send me bill ofcourse i need to pay them for bill plus shipping :)

Enjoy rest of your day!
