Good luck with an ID. The actual pictorial part of the design may not help since you will likely find generic similarities. I think it will be the inscription that gives you the best pointer and maybe even then not a date. I'm having great difficulty reading the other part. My reading, starting from the last letter of a word at the broken edge would be:
? (possibly a D)
+
E (I’m pretty sure)
? (possibly a C)
? (possibly an O)
? (possibly a C)
+
? (possibly a G)
? (possibly an A)
? (probably an R)
Z (probably)
Z (probably)
E (I’m sure)
N (I’m sure)
+
The double letter I’ve assigned as two Zs are ‘backwards’ (allowing for the fact that a seal has backwards letters anyway) but I can’t see them as anything else. They’re very angular and quite unlike the very obviously rounded S on the other part of the legend. I mentioned ‘blundered’ legends on another post, so I think the Z letters are probably blundered.
Note also that apart from the archaic font and uncertainly about spacing, there are two additional problems in reading. One is archaic spellings. The other is that words are commonly abbreviated, requiring you to mentally fill in the dropped letters. For example Nürnberg (Nuremberg for English speakers) often appears as NORNB on old tokens and jetons.
If the middle word is GARZZEN, then it might be intended for Garssen in the Lower Saxony part of Germany, but a that's a long way from Bavaria.
