Hello,
Recently I saw that there are coins from France - Kingdom in France.
After the revolution of 1789, the French Empire was founded and later restored the monarchy of Bourbon dynasty. And there were 3 Kings - Louis XVIII, Charles X and Louis-Philippe I from the Bourbon dynasty and only kings of France. But recently their coins are in France in the catalogue.
And I think it will be okay f these coins will be removed from France and placed in France - Kingdom.
When third-level countries come in, we'd probably have separate countries for the Ancien Regime (currently listed as France - Kingdom), First Republic, First Empire, Second Republic, Second Empire, and whatever comes after that (well, Vichy, but I'm not sure how many countries the rest of that period comes out to).
But before that happens, our best options are probably either the current split or just lumping everything together in one France entry. And if not for my current race to 300 countries, I'd personally prefer the latter (which is the case, for example, with Portugal and Bulgaria).
