On a different subject, I have been studying the obverse 4 missing leaf types where all the examples that I've seen bear slight traces of the "missing" leaf and a weakened linear circle above the missing leaf. The example in Michael Gouby's book, however, shows a complete linear circle:
However, close examination suggests that these 2 pictures are of the same coin - compare the shading and the dark spot on the right hand side. Perhaps the 2nd picture was doctored (definitely not by Michael) to illustrate what the missing leaf might look like. Michael agrees with me and intends to include a different picture in any future updates to his book.
I therefore think that the genuine missing leaf types look like this, with weakened linear circle:
Which is probably what would be expected from a partially filled die in that area of the coin.
