France 185x W 10 Centimes Sedan Satirical Engraving

Got this recently from a local shop. I'd heard of the "Sedan" satirical carvings mocking Napoleon III's loss to the German Confederation, but this is the first I've seen one
with the "Prussian helmet" type carving.

I think the "1870" date is just punched in for the year of the battle. The original date is
obscured, but the W mint mark (Lille) I believe was minted 1853-1857.

I wonder if the coin was carved contemporaneously to the battle, or later.
The base coins are quite cheap, so if the carved ones were popular, there may have
been a cottage industry carving them even much later.

Here's a 2 Francs I got earlier protesting the defeat with punched lettering:

And here's an 1807 5 Francs from someone who didn't care for the first Napoleon:


Finally here's my only coin issued by Sedan, a double tournois of 1634-38.
It's a bit worn, but it was a 25 cent junk bin find from many years ago!
Please feel free to post any Napoleon or Sedan related coinage!
