Changeability and whether it will stop

There is no rest for our gardener even on Sundays. But the hot June sun does not allow anything to be done at noon, it is simply too hot.
But it gives me time to rest and to sort and examine my coin collection
And while I was sorting out the other coins, I came across a coin from 1931
It is a 10 dinar coin from the Kingdom of Yugoslavia

The Kingdom of Yugoslavia was created by renaming the Kingdom of Serbs, Croats and Slovenes to the Kingdom of Yugoslavia on October 3, 1929.

10 Dinars 1931 Kingdom of Yugoslavia

Obverse:
Head of king Alexander I , facing left.
Reverse:
Coat of arms of Yugoslavia, denomination below.
At the top of the Double-Headed Eagle is the crown of the Royal Family of Karađorđević.
On the eagle's chest are three coats of arms in one.
The upper left coat of arms is the coat of arms of the Serbs.
The right left coat of arms is the coat of arms of the Croats.
The lower coat of arms is the coat of arms of the Slovenes.

This coin was minted in the United Kingdom in London Royal Mint (Tower Hill) and a smaller portion in Monnaie de Paris,Paris, France
It is 0.5 fineness silver.
The only difference where the coin is minted is in the markings next to the inscription 10 dinars
The ones from London don't have that marking

After World War II and the communists coming to power, it was renamed the Federal Republic of Yugoslavia, and later renamed again to the Socialist Federal Republic of Yugoslavia
Abbreviated as SFRY and survived like that for about 40 years
Let me tell you this, since I was born, I have not moved anywhere, I have been living in my village for 40 years and I have changed 4 countries so far
I was born in the SFRY to spend my childhood in the Federal Republic of Yugoslavia. I spent a short period in the state union of Serbia and Montenegro to live in the Republic of Serbia for almost 20 years
And I think that's it, that the changeability has stopped
But knowing our history, I always have doubts
I believe that this seems confusing to you and to me sometimes :)
And especially when we come to coins
