KM#755 UK 1 penny addition

https://en.numista.com/catalogue/pieces855.html

 I know there are two types of 1874 UK penny; they have the same portrait but with letters lengthened. Altogether there are already 12 different 1874 varieties on here namely KM#749 has 4 and KM#755 has 8, but I have one more to add to KM#755. I have two coins (the same) I cannot add to my exchange list as there is no wide date shown for plain 1874 (there is for 1874H). So I think it should read

        1874     17 leaves, thin ribbons, large date

 Here is a picture of one of mine underneath the small date variety ...

                                                

Incidentally, whilst writing I see that similar a changeover happened for the halfpenny.
                         The penny is KM#749 1860-1874 then KM#755 1874-1894
But the halfpenny is shown as KM#748 1860-1875 then KM#754 1874-1894
 So is that correct - the new variety of halfpenny also started in 1874 like the penny, but the first halfpenny version carried on for one extra year ?

Thanks :)

As the Numista team are currently working on all UK coins, perhaps these can be amended too ...

2007  117,075,000  [blank]

 I also have all three versions of 2008 20p coin - the last of the old design (KM#990 above), the new version (KM#1111), and the undated mule (KM#1122) - and all are from circulation. So on the above link 2008 is not just sets only; there were 11,900,000 issued (with 115,022,000 of the new type) so there were not as many issued. So please add those two mintages as well - the new version is ...
