If it were all raised, I would be thinking along the lines of a rim to rim die crack, or split die, or as you suggest, some type of die gouge maybe... but being so straight and some incuse, I don't know.
Perhaps the experts can provide more information or reevaluate based on your assertion of "both incuse and raise features, less incused"... or perhaps provide you with more diagnostic evaluation techniques?
Or, perhaps it's just
PMD (a scratch) as already stated by the folks above, wish I could be of more help, but I'm out of ideas.
