I decided to look up some old Madeira coins today, and found out that there are apparently two separate issuer entries for Madeira (complete with the exact same Wikidata link).
The coins struck in the 1700s are listed in Krause under Azores but a note says they are for circulation in both the Azores and Madeira. So there should be a new joint issuer unless someone has information that Krause is incorrect.

After terifying struggle between the New Madeiran Empire and Enlightened Madeiran Principality, they finally settled the issue. There is one Madeira (once referee accepts my requests). 🙈
