Oklahoman - I'm happy to defer to your judgement; if you feel that there's enough variation to warrant a whole new page, then I don't see an issue with it.
My personal theory has always been if you handed a random person on the street these notes, would they spot the difference within 5 (or so) seconds? If not, then it's probably better being a line as it's close enough for “the average Joe”, and any differences are really for the collectors to debate.
And that's how I'd build the catalogue. An uninformed / beginner level would be able to find the right page very quickly, which most probably do by sight (I.e. photo). They might have to open 2-3 similar ones, but not like 10.
But I appreciate that this isn't my catalogue, but all of ours, and my way of working may be quite different to others. I suppose I'm sacrificing the “full authentic catalogue” for a more basic “user-friendly catalogue”.
I'm easy going with it either way though. 🙂
Might be mistaken on the note seals. Or more likely, the country. I'll keep an eye out next time I'm browsing the US notes though. Thanks for the knowledge. 🙂
