Thanks, all.
NumisEd, I will keep an eye out for more on Roger II. Certainly the Normans
inherited a cultural mixture far different than where they had come from. Only at the northwestern edge of their territory would they have felt the familiar themes of Roman Christianity. The eastern and southern parts of the mainland had Byzantine (Eastern/Greek) heritage, and Siciliy had been Muslim since around 850.
Bacchus, yes I agree, the first digit looks more like a 7 or an 8 lying on its side.
But, as we will see, this unusual combination of design motifs identifies the coin to this period in the south of the Italy. By AH 733 (1333 AD) the coins being struck were fully "western" in their design.
2. Radically Bi-cultural Coin TypesAs shown with Robert Guiscard's Sicilian tari in the first post, the Norman rulers started with stylistic "knock-offs" of coins of earlier rulers in the region, in that case of a Fatimid tari which was a traditional Sicilian type. Likewise, Guiscard struck copper follari on the mainland that hewed closely to recent Byzantine types, like this one struck in Salerno dated by Grierson and Travini to 1076-1085 (MEC 14, 68):

which clearly copied this Byzanine follis of Romanus IV (1068-1071, S. 1867)


But Guiscard's successor on Sicily, Roger I (1085-1101) began fiddling with the tari design, placing what looks like a letter T (or tau), but may have been a modified cross in the center of one side, while leaving Arabic inscriptions in place elsewhere on the coin, including even the Islamic profession of faith on the reverse (MEC 14, 83-86)

Guiscard's successor in Apulia and Calabria, Roger Borsa (1085-1111) was more subtle, just inserting his Latin initials in the center of a traditional "bull's eye" Islamic design (MEC 14, 102, N#558732):

As we saw at the end of the first post, by the mid-12th century, designs featuring an image of a Christian figure (in that case Christ), but with an Islamic legend reverse, had become common on follari. This one features St. Demetrius, a Byzantine patron saint, and an Islamic legend reverse (unfortunately illegible on my example) on a follaro thought to have been struck at Bari (MEC 14, 188):


(an example in better condition can be seen here:
