Higher grade specimens can have fuller breasts!
 
	I believe that the 1860/59 is a single die pair.
 
	Reverses always have the weak legend, especially in BRITANNIAR, and even on higher grade pieces. The clover is also detached from its stalk, although that feature is also seen on other years.
 
	Obverses, whether full 6 or partial 6, always have identical marks under Victoria's chin, and again under her pony tail. They also have the doubled tie ribbon.....which isn't really a tie ribbon but a clashed die, as explained in Peck Page 404, and better on MG's website.
