My experience is that a very shallow chin cleft can appear or disappear depending on photo resolution.
I have a couple of other Anson scans where you can barely see it, others where you can't see it at all. I have never been able to find anything written about how stable a shallow cleft is. Of course a very deep cleft should be visible (unless it was washed out which was sometimes done in the 19thC).
