LOL... this is a great story of technology and espionage! Apparently some U.S. defence contractors got suspicious of the coins which they found in their rental car while traveling here in Canada. The coins in question are the commemorative Rememberance Quarter of 2004 (on the right below). The quarters, as you can see, have a very distinct red poppy in the centre which appently also fluoresces under a black light. You can read the entire story here.
By the way, I do understand the need to be paranoid if you are a defence contractor. Guys... watch out for the 2006 Cancer Ribbon coin too!
