May I then propose "Daler"? This was the Norwegian (and Danish) currency used in the period 1544 - 1875. It literally means "Valley's" or "From the valley's). I think Dollar originally derived from Daler. So then we could claim that the European Daler really is not subordinate to the US Dollar, as the Daler is the older name ... And we could get this positive, up-beat name-recognition

Same as Slovenia did when they introduced the "Tolar" as their first currency after independence in the 1990ies (if I remember correct)
Or we could just use some form of "money". The first Norwegian currency, first created by Olav the Holy in 995, was called "Penning", meaning just "money". This was in use in the years 995 - 1387. Then there was 150 years of monetary chaos due to an unstable union with Denmark, and much rebellions and such. Before the "Daler" came in 1544. Usually the Daler had an officiall pre-name like "Riks" ("National") or "Specie" ("Special"). Then we threw out the Daler and introduced "Krone" ("Crown") in 1875.
The really funny thing with having a European Daler, would be the fact that Norway is not a member of EU and is massively against joining any kind of common currency
