Yeah that's what I thought, obvious really. But what put me in doubt was the thought that if something is to the left of a bead then it is also to the right of a bead, AND in fact to space. But your inclusion of the word "slightly" has shed some light. So it really is a very fine line, which would require very close inspection. I think it's enough of a chore going through every coin, but to look at a lot of them in that detail.. I'm not so sure whether it's worth the effort.
Thanks for your speedy answer, very much appreciated.
