Issuer search for ANS gold coin (Papal States, Bologna, HRE, Italian States)

http://numismatics.org/collection/1937.146.1795

ANS lists it as a Bologna Papal States coin, which I would consider very surprising if true. I want to add it to Numista, but I highly believe it has to go in a different issuer. But which one?

Very strange legend looks like someone made it first then didn't have enough space for the portrait 😅

Imp(erator) Consta(ntinus) A(ugustus)

Have not found any coins from some Constantine looking left that look anything similar though. Maybe a fake/fantasy/medal what not.

Salve, in rete ho visto che non è propriamente una moneta ma una medaglia d' oro coniata a  Bologna del valore di 2 Ducati per l'incoronazione di Carlo V del 1530.Quindi penso sia attribuibile al Sacro Romano Impero.

Hm, coin or medal. Tough question. I wonder on what  the alleged denomination is based…

2 ducats is just a weight

Auction listing says medal…

Indeed, it looks like the model for the radiate bust of Charles used on some of his later Low Countries coins:

N#42350  

Agreed the wording is strange.  Maybe the meaning is constance (steadiness) rather than something having to do with Constantine.  So, “an emperor steadfast in peace?”    

Anyway, since it's a medal apparently, I'm not interested in adding it myself. If one of you wants to, you're welcome of course.
