I think Jeff's coin could be struck on a 1622 Batzen of Zug, Swiss Cantons. Here is an image.

Looks like this is the "host coin": Switzerland/Zug Canton KM #20 silver dicken. I matched it from the reverse exergue:

CVM · HIS · QVI · OD[erant] · PACE · ERAM · PACI[fic]

This translates to "I was peaceful with those who hated peace" (per Krause 1601-1700 catalog).

I am not 100% certain, but the confidence level is 99%, based on a short inspection, that the host is (at least) a douzain of Navarre (St. Palais) or Bearn (Pau and Morlaas).

There may be multiple recoinages here; one of which is most likely from Bearn or Navarre. What signals this attribution is the legend of the cited example which includes the letters "Q SVM" I don't see a reference to any douzains for 1622 for this province (only eight ecus, which are heavier), so if actually 1622, that may be a third strike from a royale or other series.

I have seen Dutch coins and a couple of other French provinces as host coins, but these other provinces are encountered less frequently and the legends on the example cited don't seem to correspond to the other provinces, whereas from the legends I can identify, do correspond to Bearn/Navarre.
