Single page for multiple Pick numbers - what's your opinion?

I've seen a few pages combining multiple Pick numbers, like this one. I don't see a big issue doing this as long as it makes sense, i.e. there is no difference in description, actual banknote (but why different Pick numbers than?). Just wondering what others think about it.

There is a different Pick number when there is a different imprint, among other reasons.

Can we please though separate specimen notes? I dont think these should be together with issued notes

A specimen has the same P# as the issued note. At this time specimens of issued notes will have there own dateline in the issued note listing. This is how Pick and TBB and most of the world organizes specimens at this time. Replacements also are listed with issued notes.

Of course specimens of unissued notes should have their own page...and good arguments exist for color trials having their own page.

Specimens and replacements will be listed with issued types at this time.
