I read through quite a bit of the Niue thread and it seemed like there was a lot of hair splitting going on in there. Now I’m not sure if the catalogue filters were improved as a result, but…
we know that niue uses the NZ$ officially. They sell rights to private minting companies to issue in their name. If you don’t want to collect that, then just filter out Niue. I saw something about Power coin using Numista as a kind of free publicity, but I don’t buy that line of argument. As I said before, if you don’t want those kinds of coins, just filter it out.
I definitely am a firm believer that more is better and completeness should be the priority for a catalogue like Numista. As an individual, you are free to decide what you collect and use the filters appropriately. That said, I’m sure there’s always scope for the filters to be finetuned.
More Likely, most coins in future are going to be non circulating in nature as digital transactions grow. We already see that in India, UK, Europe as the number of circulation commems have virtually stopped while the lowest denominations are either dropped or completely demonetised. Even in Canada, you can still find new commemorative coins in circulation. But they are increasingly few and far between. That’s why the price of avg price of a new toonie is 6-8$ while the loonie is 4-5$ at coin shows. It’s a proxy of how difficult it is to find them these days. Moreover, there seems no appetite to increase the higher end of the circulation denominations either . if you are a strictly a collector of circulation coins, eventually you will have almost no need of the catalogue lol
