At 5'3" i'm well below the modern average for males, so height-wise i'd be able to blend in pretty easily. However, i'm also built like a retired football(not futball) player, and that would make me stick out from the half-starved natives. as i said before, and several others have mentioned, my good health and education would put me on par with if not well above nobility, so if i could stay alive long enough to get a period outfit I could pass as a visiting foreign dignitary. The pocket-change most today consider worthless would be further evidence of being part of the upper crust, as having more than two of ANY type of coinage would be extremely rare in that time, especially coinage the size of an American quarter. If you were wearing any kind of jewelery, your membership in the royal class would be completely unquestioned.
