Darryl, I tend to lean toward's Tom's line of thinking.
I'd smoke one and see how they are. That way you can say something like "they're not bad at all really, but I gotta tell you, they're counterfeit cc's"
My guess is that they got them in Cuba, and as such, they're very likely made from very real cuban tobacco, so they're as "real" as any other cc. As such, and after looking at your dissection, I bet they're gonna smoke pretty nice, even though they're not going to be true to the marca.
If you have another box handy it might give you opportunity to show them the differences like the cardboard insert. My guess is that since they didn't bother listening to you last time when you tried to explain things to them, they just think you're full of sh1t, ya know? Folks that aren't involved and invested in this thing like we are would probably think a little thing like no date stamp and a cardboard insert doesn't really mean anything. Honestly, it might even be laughable to some people.
I'm sure you can think of a very tactful way to thank them and educate them.
On top of that, I bet you're going to have some nice, interesting homegrown cc's to smoke. Make sure you let us know how they are.
