Nice!
Its a funny symbol. I guess it just comes down to individual engravers, but some (with distinct branches) do look fairly tree-like, then there's ours which look more like half a leaf hovering over a tennis-ball (or maybe a roman meatball). You'd have thought the engraver would have a straight punch that'd look more trunk-like than a dot/ball, but nooo ...
Here's another one I just got - still sitting on my desk, with the branch symbol which also shows a lot of variation. On the Gloria Exercitvs the vertical palm branch fits the available space nicely, then on the Vrbs Roma and Constantinoplis normally we either get the angled palm branch or the non-palm "triple branch" that the greater amount of space allows (interesting that the brief seems to have been for any old branch - palm or whatever). I bought this particular specimen because it's amusing that the engraver stubbornly went with a vertical palm branch despite the easier-to-fit angled choice!
