Looking for currencies for collection (Lagos)

Dear All,

I have been collecting currencies since 5 years ago, I have currencies from over 57 countries (mostly from America and Europe) but I haven't had the chance to collect from Asia and Africa.

As I have seen that our community is full of expats from those regions, I would like to ask if anyone is willing to trade a small value note from any country for a beer.

I will appreciate your help guys,

Have a nice weekend,

John
