“Et Tu Brute” Coin … And Money From Deepest Known Wreck Site
Brutus issued the stater, which depicts him standing with two of his officers, when he was Roman consul in Thrace in the mid-1st century BC. The reverse shows an eagle holding a wreath in its clawed foot.
The silver pieces-of-eight came to light during a search in 1992 for the US space capsule, Liberty Bell 7, which sank in a sea test during which space pilot Gus Grissom almost died.
An unidentified anomaly at a depth of 16,300 feet turned out not to be the space capsule but a wooden sailing ship.
Exploring the wreckage with a robot arm, salvors discovered a chest containing more than 1300 pieces-of-eight and a small ornate box containing gold coins that had been wrapped in a newspaper dated August 6, 1809.
