Not that I know of. Just no letter or AB or BB
like on pages above and below. Even the one above looks like B but it is one B overlapping another.
So not side-by-side or directly on top, more one B moved
slightly to the side.

The BB on that first image can be seen one on top of the other, and in a worn coin may not be so clear, so could be mistaken for a single B perhaps (like in second image). Do you have a picture?
