The difference can be distinguished by spotting the top-left of 熙. So it is more likely A & B: 16.199, C & D 16.200 (OR 16.201 if there is a large dot on reverse side)
FD#955
The difference is on the "hat-like" part of 寶 . If the hat looks like a half circle then it is 16.193; If it looks like square-ish (somewhere between a circle and square), then it is 16.194
So A should be 16.193 and B be 16.194
FD#972
Same as last coin, the hat-like part of 寶 will distinguish. For A coin, the "hat" extended outwards whereas B did not. Therefore, coin A should be 16.224 and B be (most likely) 16.225 (if not, 16.223)
