The king of Calicut wrote to the King of Portugal in a letter sent with Vasco da Gama “Our state is rich in spices like cloves, ginger, black pepper, and precious stones. We expect you to pay us in gold, silver, corals in exchange for our spices and precious stones”. Vasco da Gama sold the commodities in Portugal, which he carried from India. He could earn a huge amount of money in that trade which was sixty times more than the money he spent for his return journey to Portugal.
