Anyone know if there are any decent references on the size of the BP on various sovereigns (mostly young head I guess).
My most recent McDonalds (22nd edition) says that 1871 has large and small and that seems to be as far as it goes, and David Briggs' book mentions that from 1880 onwards there are small and tiny but it doesn't seem to elaborate on it. The small seems to be thick with stops and the tiny seems to be thin with no stops.
I haven't heard of the Tiny BP, but I suppose if you were to take into the different sizes of the Small BP, some would be different sizes to others, if only in appearance due to die fill or strike weakness. The Large BP on the 1871 London and Sydney appear to be the only major variety of the BP in my books.
To answer your question, there are no references that I can think of offhand, but I suggest you could use the PCGS pop report to examine dozens of different images to see what is out there.

Yeah I've gone back and looked at some images and while there are BPs that are smaller than the normal, measuring the rough location and size of the BP suggests that the tiny BP is just a partially filled normal BP.
