17th Century Nuremberg Caesar Silver Gilt Cup Find, help with ID?

[Spartcom5]

I found this cup recently and I think it may be quite special. I believe it to be a 17th century piece depicting several Caesars throughout. It is an absolutely amazing piece and I had no idea how old it might be until I did some research. I am hoping to get more help here especially with the maker mark and pinning down a better date range. Any info provided would be of great help.
