Silber Groschen vs. Silbergroschen [solved]

The numista catalog contains a lot of coins of both variations. Especially Prussia. 

This causes issues with searching, because when you search for coins using the “Face value” filter - you will get some coins searching for silbergroschen and others searching for “silber groschen”.

I would like to create catalogue update requests for all coins that I come over that are “wrong” - however - that would mean I need to know what “wrong” is.

Personally, I prefer “Silber Groschen” - although a google search for both variants clocks in at about 65k “Silber Groschen” vs. 125k “Silbergroschen”.

What say ye?

One is correct German the other is neither correct German nor English, then it would have to be 'silver groat'.

Yes, I would have to agree. 

The correct form “Silbergroschen” should be used throughout.

All the Prussian coins have SILBER on one line and GROSCHEN on the next without any hyphen to indicate they are a single word. However, stamps such as this have the abbreviation SILBERGR with no space between the R and G. This implies that both versions were in use. One may be correct modern German but are we sure the same rules applied in the 19th century? It would be nice if we could find some official document from the period to see what form was in use.

That is pretty convincing. The same analysis gets it right for Thaler vs Taler (the latter virtually unknown before the spelling reform of 1902), so it should be accurate.

From wiki it would be attached when spelled in titles and face value fields

Lettering field is a copy of what appear on the coin, whatever variations, whereas titles and face value should use consistent denomination in FR or EN
