Palatinate - Zweibrucken - 3 Kreuzer Legend

Probably Count Palatine, Duke of Bavaria blah blah bah.

Added:
To be more serious ...
CO PA RH is almost certainly Count of Rhine-Palatinate (Comes Palatinatus Rhenani).

The DV probably relates to a ducal title, but the question is which one?
He married Magdalene, the Duchess of Julich-Cleves-Berg in 1579, so perhaps he claimed a ducal title for these places, but Julich in Latin IVLIAE, and Berg is usually MONTIS in Latin (so, DV I C M)

I am sure there is a German catalog which has all the titles for these guys, but I do not have it.

Maybe change your title to "Palatinate - Zweibrucken: Unknown Titles of Johan I" and someone else will respond?

I would assume the coin type being discussed is one similar to this one on Numista: https://en.numista.com/158193

Numista, unusually, has not offered a translation of the legend like they usually do. Perhaps because nobody's figured it out fully yet.

On the emperor's side, the letters after "IMP" are not among the usual Imperial titles, such as seen on coins from Austria for example. "P F" can only be a harkening back to the ancient Roman imperial titles, where "P F" meant "Pius Felix", pious and happy. "DEC" I can only assume to be "Declaratio", indicating that Rudolf II had been "declared" emperor on being elected as King of Germany, but never actually "crowned" as emperor by the Pope as was ancient custom (the last emperor to actually be coronated as such was Charles V in 1530).

On the prince's side, CO: PA RH is certainly "count of the palatinate of the Rhine". "DV." is Dux, or Duke, and "BA" is Bavaria. My best guess at "C. V. E. S" would be "Count of Vendez and Sponheim".

In a tradition going back to Count Stephen in 1459, all his descendants had "Duke in Bavaria" included in their titles, even if they owned no actual land in Bavaria.

I've tried to edit the topic's name but it seems that it's not possible after 24 hours of the creation time.
