The chip on the right is N1908, post fire, according to TCR9. It is hard to tell if the chip on the left is N1907 or V7773, both pre-fire. The difference in the 2 chips is in the lines forming the lion's mane. On N1907, the lines are barely visible. On V7773 the lines are distinct, as they also are on N1908. Does that clear it up for you?
