For our own collections we get nice breakdowns on the My Coins and My Banknotes pages.
But as it is impossible to search the whole catalogue (using "all issuers"), we rely on occasional numbers from Xavier for different types. It would be nice to have a kink of dashboard for Numista to see the amount of local or commemorative banknotes or the spread of the number of types issued per year. Or maybe not being able to search "all issuers" is an unreported bug ... because then I could do the filtering myself.
For example, I'd like to know how many Standard banknotes we have cataloged (my main focus) ...
Just call me Bram
No new swaps for the moment, still too many half-ongoing swaps to clean up!
I ran into the same problem with coins. Wanted to know how many of each coin type there were. Figured out it works if you use dummy year range like -1000-3000. Looks like 14845 standard banknote types in the catalog:
I remember in the past the 'all country' search has worked. Maybe it was disabled to not strain/use less server computation ... like in the past you could change to amount of simultaneously displayed items to what ever you wanted/ your system could handle not only 100. Now the max is 200.
