Do people collect paper currency and is it worth anything?
yes. in fact i do. well, it depends on the purpose of the person who collects the currrency because in my case i personally collect it as a souvenir from the country i have been to. the worth on this collection depends on how you value this activity. for some people, it is just merely to have something in their wallet or purse which they cannot really spend without having it changed to their local currency but to others it is a very precious collection which they can always look back. and who knows in the future the value becomes greater due to the time span?
