Elizabeth II British Sixpence (1953-1967)_PLEASE help with variety

[java_lt]

Can anyone help me, please...
coins (by Krause - KM#903), I did not find info about coin varietiy anywhere.
Reverse: between the initials of the engraver is the dots (E·F and C·T), but in 1966/1967 there are no dots (EF and CT).

thanks,

Hi java_lt.

I think this variety is due to a filled die. I have just checked three 1967 sixpences. They all have the dot between both pairs of letters but it is very faint and only visible with a loupe.

These pictures are the best I can manage. Have you looked at yours under good magnification?

Regards,
Jon
