In 2013, the coins were recovered under contract to the UK Ministry of Transport in what's been described as a "world record' by DOS for recovering anything at this depth, and has only just come to public attention.

The record breaking deep sea divers left a plaque at the bottom of the sea which read:
"We came here with respect."
It's now 2015 and the silver coins on board the sunk ship are worth $50 million, according to The Telegraph.
