Münzkabinett der Staatlichen Münzen zu Berlin usable now? [Risolto]

I'm a bit confused currently.

I know that people tried to get permission from the Münzkabinett Berlin to use their pictures for Numista for quite some time, because they just have an amazing collection. But it was always declined.

They had a few coins which had no copyright for some reason, but these weren't a lot.

But now, all coins I find in their online catalog have the Public Domain Mark 1.0, which basically means there is no copyright.

Just some random example: https://ikmk.smb.museum/object?id=18227706

The important text is below the picture (they misaligned their website slightly, which means some pictures sadly get over that text).

I looked at their website not too long ago with normal copyrighted pictures, but now, I can't find a single entry with a picture that doesn't has that Domain Mark 1.0.

Did they change something recently? Because that would be huge.

And as I see it, we could already use these pictures… immediately. But it would be nice to still mark them with the correct source and link instead of “source from somewhere else”.

Or is there something fundamentally that I'm getting wrong here?

Munzkabinett zu Berlin is already in the authorized sources list, I used it massively for Carolingian section :-)

Compendium

Münzkabinett Berlin is on that list for years already. But I know from pejounet that Numista didn't have the right to use all their pictures. He tried to get permission multiple times, but it got always declined. From what he told me, you can only be entirely sure to use a picture if there is some special thing going on or if the source is on this list.

And the Münzkabinett Berlin isn't on this list.

So I'm basically asking if something changed to such a degree that it can actually be added to that list.

Ok sorry then I miss context and let Xavier or Jarek answer as PJ is off for now :-)
