Adding CURRENCY to search filter

Hello,

I ust noticed that so basic thing like Currency is not on the filters that we can filter:

Yes, I know, that for many issuers there is only one currency at the time, so possible to set years range, but in many cases we have multiple currencies. I want to select one and see all coins with this currency to be able to set further filters.

What do you think about?

I think it is a good idea, especially for periods/countries where more than one currency was used alongside each other.

Denmark used two currencies for most of its pre-decimal history for instance. They were exchangeable with each other, but still.

Hello,
I agree we should implement this. I don't have a target date though.
The idea is already tracked here: https://en.numista.com/forum/topic62094.html
