25 Cent Bin Find: Principality of Sedan Double Tournois 1635-38?

Found this very worn coin in the junk bin:

I think it's the same as this one issued under Frédéric-Maurice.
Size is 20 mm diameter, between 2-3 grams copper.
Fortunately the "Sedan" and the fleur-de-lys on the reverse are mostly readable, or I would have been completely lost. I feel like an archeologist on these.
Sedan was an independent principality until it was annexed by France under Louis XIII a few years later than this coin in 1642 as part of the Thirty Years' War.

And for fun, another Sedan coin "commemorating" Napoleon III's loss there in the Franco-Prrussian War in 1870.

Just for fun, I tried to figure out all the abbreviations on the Sedan coin, as I couldn't find them translated on Numista. My coin is too worn to read most of them, of course.

Their example is transcribed:
Ob: "F.M.D.L.TOVR.DVC.D.BVILLON"
Rev: "DOVBLE.DE.SEDAN.1637"

Looking at other similar coins, I believe this stands for:
"Frédéric-Maurice de La Tour (d'Auvergne), Duc de Bouillon
Double (Tournois) de Sedan, 1673"

In other words: "Frédéric-Maurice of the house of La Tour d'Auvergne, and Duke of Bouillon. A double tournois of Sedan, 1673".

I wrote a bit more about the history of the coin and of Sedan and Bouillon on my personal coin blog. Frédéric-Maurice seems to have been quite the political schemer. He was raised Protestant, converted to Catholicism after marrying a Catholic wife to improve his political position, and was repeatedly involved in plots with France's enemy Spain against Cardinal Richelieu. He somehow managed escape with his life and trade his principality's independence for a lieutenant-generalship in the French army.

 

I love buying old and very worn coins and trying to decipher where they came from. Looks like fun and a great purchase at 25 cents! Edit: it does seem like it is the coin you linked.

 

Thanks! At the moment there's 1 used copy on Amazon for $150, so it doesn't look like I'll be getting one any time soon. Any guess what might be a fair price for such a book? No luck with any of the local libraries either. Not that I would expect them to have this kind of specialized material.
