Finally, Monteiro found out that a group of ships left Lisbon for India in 1533. One of them, the Bom Jesus, carried 300 people and a large amount of treasure. The Portuguese sailors planned to use the treasure to buy expensive India spices. Archeologists now believe the wreck might be the Bom Jesus. This is because many of the gold coins found were Spanish. Monteiro found an old letter in the Spanish royal archives. The letter said that Spain gave Portugal money for the trip. Two thousand Spanish coins were put on the Bom Jesus. This could explain why so many Spanish coins were found in a Portuguese shipwreck.
