I have got a lot of coins for swap, from Slovakia, Czech republic, Austria, Hungary, Poland, Germany etc...
I'm looking for coins from USA, South America, Africa, Asia, Australia.
2 € coin = 2€
I dont trade my 2€ or 1€ eurocoins for your cents or centavos or etc.....
The best thing which you can do now, is to record your collection and your swap coins on Numista. If you do that, other members can look into your duplicates list, or you can initiate a swap yourself.
