(I know users can create series when modifying pages, but as this is a more general idea I put it here. I'm not a frequent poster so forgive me if this is not the right place for the post.)
Sometimes series of standard bullion coins (American Eagle, Canadian Maple, Austrian Philharmonic) fall into different pages on this site. This could be because of a general design change, different portrait of the monarch or change of the currency. This can make it it slightly challenging to get an overview of the entire series. Searching “maple bullion” for Canada results in this:

Some country's bullion coinage is ordered neatly already: the Netherlands' gold and silver bullion coinage for example is listed separately because it is denominated in a secondary official currency (although it is not a complete list) and the United Kingdom's Britannias already have different series for their gold, silver and platinum variants.
Is there a demand for such series for other bullion series? And would people rather see it separated by metal like with the Britannias or just all coins together?
I was thinking of putting all Vienna Philharmonic coins together, because there the gold has been going on since before the Euro and different metals and sizes only appear every so often. Since there was no modern Austrian referee to discuss this with, I decided to post it here and also extend the idea to other series.
I hope this can contribute to making Numista more tidy.
