I'm always amazed with people who find a cache of gold/silver coins and they announce it to the world. All that does is bring in the weezils wanting to claim them for their own. "Oh, these coins? They've been in my family for decades, maybe longer." Put them up for auction if need be. Historians would be interested, obviously. Although in some countries like the UK you need to declare your findings and the gov't wants to take a bit.
