Update: I am now about 70% sure that the article I found was
this one (I recognize the setup). If so, I must have utterly misread it.
Here's what it
actually claims:
- the article's author believes that Özbeg had very likely only died in 1342 CE (late AH 742 or even early AH 743)
[this was seemingly the part I focused on originally]
- nevertheless, he also believes that the AH 741 dated coins of Jani Beg are probably real and probably actually dated AH 741
- (the article goes into some detail over why he thinks this is the case)
- (in particular, he suggests a plausible-sounding, though very elaborate, explanation for the year 7 date)
- there is apparently also one more possible type of AH 741 Jani Beg coins in addition to the year 7 type, though it is very scantily attested
- it is plausible that Tini Beg continued issuing coins in Özbeg's name, which accounts for the AH 742 Özbeg coins even if Özbeg actually died in AH 741
- (are there any coins
at all in Tini Beg's own name? the article doesn't seem to answer that one way or another; from other sources, apparently the answer is "no")
- it is [according to the article] also plausible that Jani Beg actually started issuing coins in
his name even prior to Özbeg's death
Other sources seem to mostly agree with each other that Özbeg died in 1341 CE and that Jani Beg was crowned in 1342 CE after a brief reign by Tini Beg (who, as mentioned, seemingly did not issue coins in his name).
TL/DR: I am also voting Aye, and, most likely, if I didn't happen to misread an article that I
also unaccountably didn't bother to link, we could have progressed back in July.
I strongly apologize for the mess, and next time if I try to do any strong claims like that, I will at least try to make sure to explicitly cite my sources.
P.S. Fedor Yermolov (Qutluq_Bulsun) on the Rasmir forums repeatedly insists, apparently on die link grounds, that the "741" coins are misreadings for 749.
Zeno calls them "probably anachronism". (Zeno also doesn't have any AH 741 coins from any
other Golden Horde khan either.) I honestly don't know what to believe any more.
