Any chance this theory is accurate?
 

I don't think that I am outing this since it has a high BIN. Also, not suggesting that the seller is attempting to be anything other than honest. Is it possible that the Sweet Caporal 350 stamp on the back could have come from the factory? I can't think of any reason the factory would manually overstamp an epdg with SC. I've never seen a collector stamped card with this particular stamp either.

I've seen this eBay listing for a while now. I don't think there is any way this is an ATC/ALC produced stamp. Why a collector would do that is beyond me, but there are an almost infinite variety of stamps that have been seen on 206's and other cards.
