Zeno numbers refer to an exact coin, not to the coin type. It would be unreasonable to add 100 zeno numbers to one coin type in Numista catalog
I have practical experience with adding the xrefs. The site has few listings of modern coins, so you will find few if any listings of those. You will find multiple listings of older coins, but I can't remember finding more than around 10 listings of a type/date/mint combination, let alone 100.
The problem may be what you call “type”. On screwed and hammered coins, this is a vague concept, as dies were hand-cut and not hardened, so many dies, each cut individually, were needed each year and I haven't even started about mules.
As an illustration, if a Roman coin is die-identical with another, this is considered as a sign that the coins may well be modern fakes. Maybe even clearer: among the “forced currency” of Muhammad bin Tughluq, sultan of Dehli there are a good number of underweight specimen. These were long taken as contemporary counterfeits, but the communis opinio is now acknowledging that they are more likely to be coins struck in provincial mints, where quality control was less strict. So are they another type?
An unidentified coin is a piece of metal. An identified coin is a piece of history.
