Last one (1767) looks a bit like this one; except it has C 7 and yours has C VII on it - but it is a start of where to look - Danish West Indies. Some of the other pictures are too blurred to look at - or write the size and what letters are readable - to help us to help you.
P.S. I see you already agree with the country, and I agree now it is 12 value (and is KM# 12 also), as on the top right edge lettering on ship side it reads XII which is like the better example below ...
Also not sure if PhotoBucket pictures are allowed, as yours are too big - perhaps only Numista server is supposed to be used, as it creates miniatures. On Reply box click Image on top right. Maybe
Finally, though it is dated 1767 that is not the mintage date.
Letter A was struck in 1795 and 1800
Letter C was struck in 1782
Letter K was struck in 1790 and 1791
Not sure where the letter is - all three are still KM# 12 and are described >
