Sorry, I have not my weighing machine here....
C1) This one is 18-20 mm and seems to be from sa'dian sharifs:


What is the reference book for sa'dian sharifs coins?
C2) This one is the smallest one (1/2 fulus?) around 12-14 mm


C3) this one is 16-18 mm


C4) 16-20 mm


C5) the latest one is quite thick (2mm) and around 16 mm


Thanks,
yvevmax
