Thanks Pete. Here's the link to that penny (I follow Topcarp he always has great coins), and that's MUCH more like a birds foot than the GV exmaples.. Didn't know it extended to Victorian series too though, is there any literature on it? This must be a die clash too, it's a lot more obvious where it came from on this type. I've got a very similar 1877 example on my website and when you see the obverse and reverse side by side, you can easily see how it's caused by a clash with Britannia's robes from another penny's reverse. (Topcarp is John Jerrams I think ?)
