This is what I got. I'm guess that's the same as yours? I don't have access to my sets right now, but I've played 6 games with adventures cards and I don't remember noticing any differences in card quality. I'm guessing I would have been able to tell with the coppers/estates mixed into the deck etc.

Heres a link to where I got it.

On the reviews it warned about poor card quality. On the box it said made in the us and from the little research I've done online it says that its because the first copy was made by hasbro and has worse quality
