it is harder to label a card "scrap" without the "fat" borders....they are the "give away" tell tale sign.....
more subtle errors and the "thin" borders put them in that "tweener" category...
as you have a very good inkling they are scrap, but can't be 100 % confirmed...
as a great example with luke, that "skinny" border scrap , a 100 % scrap since it has the blank back.....
I could bore you guys all day with examples, but I think you get the gist of it...
