Particularly western iconography on the trachea of the Latin Empire of Constantinople

Those two are really nice! The specimen I have clearly indicates that it is NOT the Virgin Mary:

I am certain I posted this earlier, but here is one that has been clipped excessively:

Are you telling me this coin depicts Peter, Paul and Mary?

 

Latin Rulers of Constantinople, 1204-1261. Trachy (Billon, 22 mm, 3.10 g, 6 h), Constantinople. IC - XC Facing bust of Christ Pantokrator. Rev. Archangel Michael standing facing, holding lis-tipped scepter in right hand and globus cruciger in left. DOC 16. SB 2036. Exceptionally well centered and struck. Extremely fine.

Not as rare but in great condition, unusual for the issues.
This whole time period gets confusing, from the Latin issues to the Bulgarian issues or faithful copies depending on who you read.

 

There is a series of these that have no mark of minting authority and that Metcalf tied to the period of Ivan Asen II and his diplomatic overtures towards Rome, minted perhaps at Veroe between the 1230s and 1241, which is an interesting hypothesis that Balkan historian and numismatists seem to favor for two basic reasons: A. not much of stamena/trachea of these types are from Constantinople itself and B. they appear in Danubian and maritime Bulgaria and even north of Danube to the Dnieper, in places traditionally of interest to the Bulgarians, and less in Thracia and Northern Greece.

On the other hand, what @Quant.Geek noticed about differences in iconography and a certain irregularity of styles, coupled with the dual modules (most if not all "medium" modules are actually cut large modules) might point to the theory of the 'Imperial mint' vs the 'Public mint' -- the latter being a 'Venetian' operation for the Bulgarian trade. The latest support for this comes from Baker in Money and Coins in Medieval Greece 1200-1430 (pp. 1227-9). The sequence provided by R. Glanfield seems to indicate around the mid 1230s.

Here's Type P and Type R large modules:


Type P Christ and Archangel Michael



Type R Christ and Virgin Orans
