The Eretnid Beyliks

This Islamic coin captured my interest with it's unusual highlight of "Allah" in an eye shape with dots from the 14th century. It is a nearly perfect strike and centering, elegant script including a beautifully executed and decorated "Muhammad" in Kufic script, clear mint and date.
This map from Philip Remler's article on these coins shows the location where this coin comes from in eastern Anatolia.

“The Eretnids have been regarded by some scholars as one of the Anatolian beyliks, but they were of Mongol origin and struck coins according to Ilkhan patterns.” (Album)
In the turbulent years following the death of Ilkhan Abu Sa'id in AH 736, Eretna, an Ilkhanate governor, turned to the Mamluks for support, minting coins referencing Al-Nasir, and eventually declared himself and independent Supreme Sultan.
"Eretna Uyghür, founder of the Eretnid dynasty, was the Mongol lieutenant-governor in Anatolia from 1314 to 1335 and governor there for the puppet Ilkhāns controlled by Hasan-i Buzurg Jaläyir from 1335-42. Between AH 742 and 746/AD 1341-46 Eretna minted coins both in his own name and in those of various Mongol khāns. In 747 he began to issue coins in his own name only." (Remler)
"As chief civilian Mongol official in Anatolia Eretna struck coins of types standard throughout the empire. Certain of these types, occurring in Anatolian mints, are prototypes for later beylic coinage." (Remler)
'Alā al-Dīn 'Alï (Ali Beg) (767-782 AH / CE 1366-1380) grandson of Eretna, appears to have become sultan at the age of seventeen. He was the last Eretnid sultan.

"'All's looped square has as its prototype the motif of his grandfather, Eretna, which in turn goes back to the Abü Sa'id Type III. Similarly, the octafoil likewise goes back to the Ilkhān Sulaymãn Type II and before that to the Abū Sa'īd Type XII. Known dates for 'All's coins are AH 767 and 768. Sometime in 768 the word Allah in the phrase "khallada Allāh mulkahu" was enclosed in an eye-shaped group of dots. That this symbol had some significance is shown by 'All's practice of counter-stamping his older coins with the same symbol." (Remler) Here's my example :
