1, I suggest the moderators move this to the Ancient & Medieval forum. Pretty confident that what we can see puts this before 1600.
2. While the reverse design is a good match for a cruzado of Enrique II of Castile & Leon, I am a bit troubled that the portrait obv seems to have a beard and quite prominent ear, which do not match the examples of this type I can see in numista. The legends are so worn that it is hard to see what is in them.
