Normal practice was to manufacture disc and shank in one, but they do not appear to have been cast into their final shape, as they nearly always show signs of having been worked (perhaps to enlarge the head and make the shank more pliable; greater technical minds than mine would need to comment on that one). Characteristically, they always have slightly raised concentric rings on the undersurface of the head, perhaps to help them grip the strap better, although it may just be a byproduct of the manner in which they were finished.
