There were many die pairs made. Not sure how many pairings were made for an 82' Philly Zinc large date. But there were many. Each of them take on their own characteristics. This is only one of the pairings. At this point in die making the Philly mint made all the dies. And sent them out to Denver to be struck. For those more knowledgeable, did Philly make the hub's only or did they send working dies?
