Admiral Gardner, sunk in 1809 off the southeast coast of England

Along with her sister-ship Britannia, the English East Indiaman Admiral Gardner was outbound with an immense cargo (48 tons!) of copper coins for circulation in India when both ships sank in a storm on the Goodwin Sands on January 24, 1809. Ten lives were lost, as was all the cargo. The coins were recovered in modern times, literally a million of them packed in wax inside wooden barrels.
