Is it just me, or are the '3's' in the 1903 open 3 penny and the 1903 florin very similar?
If any member has an example of both, it may be worth measuring the size of the '3',
and if they are the same size, it's not beyond imagination that the open 3 penny occurred because someone picked up the florin punch by mistake?
If this has been discussed before, apologies- this idea just occurred to me, and I can't find it in a search of the site.....
