It was (and still may be) a custom on ships (military and civil transport) that at the 30% construction stage, a coin is placed under or near the tallest structure of the ship. This custom dates all the way back to the ancient greeks, who dropped a coin in the mast well on their sailing ships.

The coin is used to pay Charon, the Ferry Man over the River Styx, to ferry the soul of any member of the crew that loses their life while on board that particular ship to Hades, the abode of the dead. Normally the coin is gold, but silver works too..Charon just wants his money.

I know they still do this at least when i was employed as a chipper at the shipyard in Pascagoula Mississippi. I was part of a team that permanently installed a coin beneath the Mast of the USS John Hancock. It had to be a new coin, that the sailors committee insisted.

Interesting info, haven't heard about this before.

I knew, and they still do it. I think I saw images of people putting two coins in the QE2. One English and one French. Don't think Charon will consider that to be much if that big thing ever goes down.......

I vaguely remember hearing about this while I was in high school, but I didn't know they still did it. That's pretty cool, and a very long lasting tradition...

ah yes this tradition is still strong. It died out for a while apparently, but was brought back by pirates between 1600 and 1800, allegedly they were very superstitious people.

I knew the greeks put coins on the eyes of their dead, but I have heard very little about this tradition.
