Boingboing provided an interesting link to a story about a 2,000 year old counterfeit coin found in Italy.
This little nugget caught my eye: "This is not the first example of counterfeiting in the ancient world, but the researchers say that in this case the silver coating seems to have been created by a sophisticated chemical process."
My Conspiracy-and-Hermetics addled brain can't help but draw tenuous, unscientific links between disparate bits of historical ephemera.
Thus I conclude that the Italian coin could have only been electroplated utilizing Baghdad Batteries.
I should go before I rant about how the Bronze Age first occurred in Southeast Asia or that dolphins, humans and apes had a common ancestor.
