@Reid, I appreciate your posts, and your collection.
This really is a fine mess you've found yourself in.
I'm just an outside observer and from what I can tell, bad things have happened... and you have the opportunity and ability to make them right.
Reading this thread though, a particular Shakespeare quote comes to mind... "The lady doth protest too much, methinks"..
I don't think anybody is claiming you purchased stolen goods, but the concern is very much present. It does not look good.
I do believe
@a2fan mentioned some ISAAC cards?
Regardless, this doesn't look good, and this thread is not a good look in your history. Doubling down rarely ends well...
