I can at least help with Austrian, Czech and German marking IDs and dating.

When looking for values In general one has to hold many things in mind. Chris has a pretty good generic explanation here ( [url=https://www.porcelainmarksandmore.com/resources/essays/question-value.php]https://www.porcelainmarksandmore.com/resources/essays/question-value.php[/url] ).

That aside, you should try to separate true producer items from re-decorated items. Hobbyist-redecorated items are lowest in price ranges. Higher up are studio-redecorated goods. And then we have sort of three levels of low – medium – high class producers.

This site does not enlarge pics so we can not see the marks to read them !! What most people call Limoges China just means that it was from that area and could have been decorated by anyone of a number of studios !!
Friedrich is an expert on German porcelain so he can give info on things from that area !! But to give a value would depend on many things so I usually just help with the research so you can find a value !!
I have had some pieces of Limoges that you couldn`t give away much less sell !!
The link at the top will show the marks and years used !! Some had more than one mark !! Anything you can`t find post here with a good pic of the item and a close up of the mark and I will try to help !!

Please hold in mind that people seeing “antique Limoges” will expect items coming from (and decorated in) the Limoges area of France. Items like shown in your post on the other hand are hobbyist (re)decorated items which have no connection to the original item producer, neither quality nor age-wise. You should try to find a better wording, like “stunning group of hobbyist-decorated French china” or such. That way people looking for true Limoges can stay away and will not feel upset/clickbaited.
