Diffence between "In use in..." and actual circulating coins and notes

Hope I haven't missed anything, but could it be possible to add a sorting or comment in the blue box or something like that, to tell if the coin or note is still in (widely) circulation or just not yet demonitised?

I thought of this, after I read a story about a custommer who tried to use one of the older Danish 50 kroner notes:

But this is the one we use now:
https://en.numista.com/catalogue/note202093.html
And the young cashier didn't want to take it, doubting its autenticity/legality. But as a matter of facts, it still has the value of 50 kroner (All Danish coins and notes from face value of 50 øre and up, are all legal tender as face value) But, it is not in widely circulation. If you bring it to the bank though, they will also exchange it to the current bills/coins or into one's bank account, in the same value, and the bill/coin will be destroyed/melted down, if not the banker takes it, for them self. They may collect too

The short story is: Could we get something to indicate if the note/coin (design-serie) we have, is still in widely circulation? I know it can be hard, for eg. monarcies, where there is a transition period whenever we get a new head of state, or when a coin serie change, but it could be on three levels:

Not in widely circulation.
Getting out of widely circulation.
In widely circulation.

It can maybe also be hard to define "in wide circulation", but I think this feature could be nice regardsless, since some people only collects money in current circulation and other may just use Numista out of curiusity: "hmmm... Are these notes I got 20 years ago still useable?"

As a side note, something like this, could maybe also be a good thing for still exchangeable currencies, like the German Mark? Adding a 4th to the above levels:
Still exchangeable

I would rather want some thing like start of issue end of issue and use demonetization when they can't be exchanged anymore.
The 'in widely circulation' is to mushy of a term for me there are coin and notes that circulate unofficially years after withdrawal and demonetization etc.

See https://en.numista.com/forum/topic95824.html for an earlier discussion.
At present, demonetized is used in many cases where this has not occured and is clearly causing trouble. I and others have requested that a new box be added along the lines of "Withdrawn from circulation" which , in many cases, would correspond to the withdrawal of legal tender status when this has not also been the point at which banks stopped accepting them. So far, nothing has happened, so thank you for raising this point again.
