Due to the large varieties of dates on these banknotes, the listings can't seem to decide whether to specify ranges of dates, or to make each date its own variety. I've got a banknote with a date that would fit in one of the ranges, but doesn't have its own date specified, and I've also got one that doesn't fit in either a specified range or a specific date. Is there a convention I should be following when adding them? Or is this really just a chaotic mess, in which case we should decide whether we want ranges or specific dates.
