The only occasion on which I found an obverse die match between coins with different Minerva types - see coin below. Since such links are virtually inexistent, and the style is clearly grouped around each reverse type, Prof. Carradice rightfully assumed that each reverse type was struck in its own separated officina. This seems to be the exception that confirms the rule. It is interesting that their style is very unusual, but they are certainly ancient and made of solid silver. Another detail is related to the bust type which is more of a "right shoulder forward" type instead of the usual simple head.
