oof you gotta replay then, thats the only way, dont just use pirate coins indiscriminately and dont be afraid to use your silver coins. there are stuff on trading where the price depends in each location. don't just check the percentage(rate of exchange) even when it's high it doesn't mean the price is also high. I recommend making trips a few times just to make money. I now have over 150k silver coins in bank and increasing.
