Coins can only be earned by Mercantile Claims, by exporting goods at the local Market. A representative will publish which items are going for what rate and will be present at the Market Day to do the exchange. Only the guild leader may export goods on behalf of their settlement, and must register their Guild in advance. Additional official settlement representatives may be authorized by the guild leader if they will be absent.
Of course, demands and the offered price for your goods may change over time... be it through events on the mainland or simple oversupply...
Market Days will be held on a weekly basis at Seagaard Port - until a Player Settlement reaches the appropriate Mercantile Rank in order to host it. Times are selected to cater to both U.S. and EU players - but it is usually held on sundays.
