Question Regarding The 1888-O "Scarface" Morgan Dollar

Yeah, I read through all of the stuff on VAMWorld for 1B0 to 1B4, read Ash Harrison's VamView on the progression, and watched a video of Mr. Harrison describing the progression in reverse from Stage 10 to Stage 0. I also Googled and Reddited the hell out of it, checked past discussions on here, VAMWorld, and Collector's forums. I'm hoping to get the "gospel" answer somewhere, as in if it's known what the actual cause was and not just a theory. Thank you for the info, I will add it to my growing mental pile.

@jacrispies, I have to ask with all sincerity if you're one of the people that would know the gospel answer to this? See the last time I questioned someone about the cause of a clash it turned out to be John Roberts. He actually did the Die Study for the entire mintage I was researching and I told him I thought his conclusions were wrong before I knew who I was talking to.

There is probably no sure way to know why this die cracked when and where it did. On this die, the trouble started near the dot between E and Pluribus. Could have been a strike-through happened on a coin earlier in the die life? Something created a weak spot that progressed as outlined in Harrison's review. A similar event occurred on the reverse die in the 1881S series (VAM-54)
