768 H. 1367 CE Dehli Sultans Tanka

Ok, time for more controversy. (thank me later)
I posted this coin last edition as a 767 h. (1366 CE).
It is a type G&G D474,which has dates from 765 to 768 H, and at first glance it seems dated ok, albeit with a dodgy looking LH digit.
However, on looking up my G&G catalog on something else, I read the footnote under D476 which shows my coin to be a retrograde 768. Also compare with Zeno #80041
https://www.zeno.ru/showphoto.php?photo=80041 I think andyg has a similar coin, but it may actually be the 767 H. as the LH digit is hidden.
