GROSSHERZOG vs GROSHERZOG

[Muscovite]

Hello!

Some coins of Reich have double S, but some - single, - in the word GROSSHERZOG. I can show the examples but I think you know what I mean. Why is it so?

Thank you.
Alex.

P.S. Sorry for possibly stupid question

There was no rule for writing the ß of "groß" in capitals. So Baden, Berg, Frankfurt, Hessen-Darmstadt, Oldenburg, Sachsen-Weimar & Eisenach and Würzburg used the single S.

Both Mecklenburg used the SS, SW&E did so after 1840 and from about 1900 all remaining Grand-duchies Baden, Hessen, Oldenburg joined them.

SW&E used SZ instead of SS from 1903 onwards.

In 1901 a reform of the german orthography ruled out the single s.

I knew about modern capital ß writing and was surprised when found the difference on coins because did not know about rules changing.
Thank you very much for detailed answer!
