There is something to do much better and correct in first place. As you can find in the catalog right now, there is only main category YUGOSLAVIA and nothing inside it. It can be done much better. As there is no referee for that country yet I offer myself to take that function.
I live in Croatia and I have years of experience and enough knowledge to do that much better.
Now here is a mess and it is very difficult to understand sets while looking the catalog.
I am ready to cooperate and help. Be free to ask any question regarding this country.
FLAG ISSUE
First Yugoslavia - HERE IS A FLAG WITHOUT STAR Kingdom of Serbs Croats and Slovenians (in regional language there was a change from Kraljevstvo to Kraljevina but it is just a different word for the same meaning Kingdom) Kingdom of Yugoslavia
There is no "serbian dinar" in Yugoslavia. It is a currency belonging to Serbia.
Second Yugoslavia
Yugoslavia had almost the same flag with a red star from 1945 to 1992.
Democratic Republic has it a little different, only inside the white part of the flag, while the People Republic and Socialistic Federal Republic has it bigger, over the red and blue. But that is not a big difference.
War begun in 1990 and that was already the end of Socijalistička Federativna Republika Jugoslavija but not officialy. The banknotes from 1990 and 1991 already lost that inscription on the banknotes and instead is written only Jugoslavija. This emission is something that have sence to call transition dinar.
Third Yugoslavia
The new emission called here Reformed dinar has to be again under a flag without that star.
In attached images you can see that change.
I have created a correct suggestion and will attach it tomorrow in the next post in this topic, to not make confusion. At the moment this is the correct suggestion only for categories and flags.
Here is a very detailed and precise categorisation connected to the last post in topic.
Bolded text are categories and italic are currency.
There are a lot of emissions and many similar but completly different banknotes. This way is well organized and very clearly presented, to collect in sets, matching P# catalog numbers also. Many times there are mistakes made in world catalogs. I have made all needed corrections. If someone has a question about anything, be free to post your doubt, questions, suggestions...
Did you check the ruling authorities we already have? If you go to display options / order by rolling authority? They are almost the same with the ones you propose.
Series are unfortunately not available yet for circulation currency, only for commemoratives. But when the become available, for sure the structure you propose make sense
Off course I saw the rulling authorities. That is preatty nice but I don't understand why that are not subcategories in the country three like for other countries (example Poland). Unfortunatly it doesn't help to make order in the catalog. In the catalog everything is ordered by currency right now. That is the reason why I organized currencies better. That way sets has been made and it has sance. Otherwise you could create only subcategories of Yugoslavia and only 2 currencies, Dinar and Kruna.
I have added some missing banknotes and corrected mistakes and errors in some other, also uploaded better images of my UNC notes.
I hope something will be improved for that country because it is my and many others main collection and it is very bad as it is now. Everything mixed together and not clearly.
Use Poland to compare. There has been made a vey nice job.
Maybe my idea is not completly clear. In the suggestion I posted P# are listed just to show how that would be nice organised. Not to create that like a category inside subcategory.
I meant to create subcategories for Yugoslavia and inside them organize everything in sets by currency type like it is now but much more different more detailed currencies. You can see now is organized by currency (not by rulling authority).
Look like Poland have been made:
Indeed, Yugoslavia would benefit from more structure and thank you for your ideas to improve this section.
However, what you propose is not in line with how we generally divide countries. As a general guideline, we split countries when there is a discontinuity or when there are several issuers that existed in parallel. Poland is a good example: the Kingdom of Poland issued coins until ~1570, then it became part of the Polish-Lithuanian Commonwealth. Then Poland started issuing coins again around WWI. This 300+ years gap justifies a split between the Kingdom of Poland and Poland.
If you look within Poland, you will also see different forms of government (Regency, First Republic, People's Republic, etc). And this is very much the case with Yugoslavia as well.
The idea of having series has come up several times already, and I think it will help organise the catalog better.
