I have identified this as german due to the 13 mark and possibly bavarian due to the pine cone mark?
I cannot seem to identify and date completely, so any assistance is greatly appreciated.

The mark above 13 which might look like F is just struck weakly. I think it's a shield which has a lion's face (or some other animal). You can compare it to a London silver town mark to see how it probably should look like. London mark is well known so similarly styled marks have been used as a pseudo marks.
