U.S.-speculated Canadian "spy coin" was Poppy quarter
"filled with something man-made that looked like nano-technology"

They did look at the coin with a high-powered microscope, but still. So much for American intelligence! We're really under the radar here, we should exploit this situation.
Help me find with a cheeky LJ tag for "intelligence".
