 It was later proved in trial that the recovered cargo was being carried by the Spanish frigate "Nuestra Señora de las Mercedes", which sank off Portugal in 1804.Knowledge of the recovery became public on May 18, 2007 when the company flew 17 tons of coins, mostly silver, from Gibraltar to a secure location of unknown address in Florida, USA.The company did not release the type, date, or nationality of the coins, while a rumor attributed it to the "Merchant Royal", which sank near Land's End in 1641.
