Unrecognised? Farthing Varieties (1870's)

Hi all, I've noticed that the British seemed to have problems fitting in the obverse legends of some of their farthings in the 1870's (at least). This has resulted in a couple of interesting approaches (that don't seem to be particularly rare).
Note that both the approaches below occur for dates where the full legend is displayed normally - ie these are varieties although not even Peck describes them. I'd be interested to know of a catalog that does include these - any help here ?

method 1: 1874H,1875H, 1879:
Chop the bottom stop of the last colon neatly in half:



It's a bit blurry on the 1875H above - here's the detail from one dated 1879:


Method 2: Remove enough from the back of the portrait to permit the full colon to be included.
This example is on an 1878 farthing
