A time capsule at West Point that was initially thought to contain only dust actually held hidden treasure. The lead box, believed to have been placed by cadets, contained six silver American coins dating from 1795 to 1828 and a commemorative medal. The discovery was made by West Point archeologist Paul Hudson, who carefully sifted through the sediment in the box. The find confirms the theory that the box was left by cadets in 1828 or 1829.
