Having looked a bit more into this, I see a one problem with the 1574 Henry III teston. The first royal decree about manufacturing coins with Henry's name is dated 7 January 1575. So, any coins with Henry III dated 1574 would strictly speaking be illegal. And even if the Nantes mint master would be a big fan of the new king, it would have been difficult to begin minting his coins prematurely since at this time the master dies were manufactured in Paris, and that would not have happened until 1575.
So, in conclusion, I doubt that the 1574 coin that Sombart mentions is genuine. Either a forgery or an engraving mistake, I think.
