Interesting idea. The thing to do is check late hypers for something like the name "Andronik" on the right hand
side.
I checked all the
John V & VI
types in my files and couldn't find anything like this.
I also checked all the "Avtokratores Romaion"
types of Andr. II & Mich. IX, but they all seem to be kosher.
Another possibility is that some of the rarer
types attributed to Andron. II & III are actually
John V and Andron. IV, but I found nothing convincing there either (but see below).
A single ruler
type of
John V in the
style of Andron. II alone would presumably be pretty obvious.
Given that there are actually quite a few
John V and VI hypers floating around, if these
types were also issued in the name of
John V and Andron. IV (or
John V alone) I think we would have expected to see some by now, and so I have to doubt they exist.
Perhaps the currency was based on silver in the period before the
stavrata, but none of the
basilica in John's name seem to be belong here (they all have Anna on them).
There is of course the famous gold florin in the BN, but most people think that is a
fake, and it's hard to take it seriously without more examples.
Finally, note the interesting
type assigned to Andr. II and III with
siglum 12. On recent examples of this, like those shown below, there is a beardless junior ruler on the right, and
Bendall suggests (in Num. Circ. 2004 in fact) that this is possibly an issue of
Andronicus III and
John V (on the basis of a doubtful reading of the legends on the GM coin).
Could the junior ruler perhaps be Andron. IV? Don't know - but the legends on the NAC 51 coin (which
Bendall hadn't seen) look more like John and John to me.
Hmmm - I'm not sure I understand all that, but I
hope it helps.
