Hello!
I would be interested in swapping very common and low value coins: the idea is to swap those you would seldom choose in a swap because you find something better in the partner's list. For example I would swap former currency (i.e. francs, lire, marks, schillings…) with the equivalent from South America, Asia or Eastern Europe.
If from out of EU I propose to send light letters (< 100 g) via regular mail with stamps (the old way, no customs declaration!).
If anyone likes the idea, just write me message.
