Die cracks are very common on the old cartwheels. It takes about 150 tons of pressure to strike them, so the dies take a real beating. There are a few collectors here who are well-versed on the Morgan varieties (called VAM's). Perhaps someone like @messydesk can help you identify your coin. Chris

You might not ever. Or you will find that it is minor. All die cracks, clashes, errors. Etc., get broke down by their die pairings. It's quite the venture when you are trying to attribute them.
Better than looking at the die crack, look at the 'r' in trust to see if it's whole or broken. Then look under the eagle's right (viewer's left) wing to see if part of the wing was re-engraved. These are my first two "go-to" spots on a 78-S when attributing one.
@messydesk might say otherwise, but die cracks are seldom used to attribute a VAM. They are generally used as contributing diagnostics.
I think I have the B reverse with parallel feather but apart from that can't find any more info,I know I have seen this die crack on YouTube but don't remember if it was coin op ,blue ridge or other
