Tsardom of Russia, Grand Duchy of Moscow and Russian principalities

Hello.
I propose to add in section Countries and territories "Russia" three new territories:
1. Tsardom of Russia
2. Grand Duchy of Moscow
3. And Russia - Feudal coins (the example of France - Feudal coins) or simple: Russian principalities. There I propose to make different Russian principalities.

I purposely did not offer to create Kievan Rus', will do that later.

https://en.wikipedia.org/wiki/Kievan_Rus%27

Thank you for your advice, attention and possible amendments.

Of course, if we have new countries to fill gaps, we'll have to create them, and I'll try to suggest it in the Board before the meetings. Is there already coins from these countries already listed? Or do you expect to do so in a near future?

Now there are only a few coins. And yes, I'm planning on doing in the future. Maybe not just me. I hope.

Can you provide us links of the concerned coins and their affiliated future country?

For example, for Grand Duchy of Moscow - https://en.numista.com/catalogue/pieces49181.html.
For Tsardom of Russia - https://en.numista.com/catalogue/pieces84866.html

Don't worry, I only asked you to know which ones would be able to be launched asap and also ease their creation.

As far as I can tell, this type and this type also belong in Grand Duchy of Moscow (the division point is 1547).
Note that this type belongs in Tsardom of Russia (compare the legend); I'm not sure why it's listed as pre-1547.

There are no coins I can see in the current "Russia - Empire" listing that would belong under the "principalities" (there are many such types, some of which I have in my collection, but I don't think any have Numista entries... I distinctly recall seeing some a few years ago, but I can't find any now).
