if your having trouble with the pics it is probably too large .
you will have to decrease it's size, either by mailing it to yourself & then
copying it into your file, Or with a photo edit program.

as for what you have, I'm sorry to say every person in the Government,
and almost everyone who reads Treasure Hunting sites (almost Not all)
have been conditioned/brainwashed to believe they are all counterfeit.
So essentially , no matter who printed them in such a large amount.

the U.s. to Scam
someone, The CIA, to scam someone.
or if you would believe the stories they tell you.
that some small time counterfeiter who didn't have experience
happened to have a Ton of paper & Boxes ,
a Printer & Time. so he concocted this whole thing while sitting in his Shack.
I myself prefer to believe the Errors were placed there on purpose.
so declaring them counterfeit, instead of owning up to the debt.
Could easily be backed by saying "look at all the Mistakes on them"
the point is, they have been declared counterfeit by the U.s.
that pretty much means they can arrest you for having them if they want
