Startup Idea: Foreign Currency Exchange Platform

Startup idea to develop a platform enabling travelers to exchange their leftover foreign coins or bills for usable cash. A useful tool for frequent travelers who accumulate unusable foreign currency.

A lot of people are bringing coins back home from their trips. Of course, no bank is taking them back and there is nothing to do with them a part of giving them to charity.

So I'm thinking there could be some sort of software/platform/system that could bring people together in order to exchange these foreign coins/bills against actual money that they could use.

The people that would need it would be people that are going abroad and that will enjoy to have some cash with them upon arrival.

I haven't found a solution for that. Most banks are only taking back a few bills but never take coins..and I know a lot of people who have the same problem. Would be really nice if there was a way to exchange this money back without having to either: get back to the country they're from give them to charity leave them in a box forever.
