Napoleon Empereur 10 CENT evaluation ?1808

I attach two photographs of this billon coin, 19mm diameter, with all detail remarkably clearly readable and I believe the date is 1808 and similar to the one shown on Numista (en.numista.com/catalogue/pieces1139.html but the lettering below CENT is different.

My coin, observe, crowned monogram within wreath. Lettering N
Reverse, NAPOLEON EMPEREUR 10 CENT . Below this appears two letters one of which may be a symbol. I do not know what the left hand one is but the right one is an A. Maybe these are Mint marks and info on this would be of interest. The date below in the outer ring is I believe 1808.

I expect this may be a valuable coin and collectors item, and more information on this would be appreciated, likewise views as to its likely value please.

Many thanks.

​ So coins made in Paris have the A letter, and alongside it an emblem of the mint master - such as a rooster (like on your coin) or when he left then an anchor or a pointing hand and so on.

​Indeed, a very interesting coin!

This would be one of the last 10 centime denominations that circulated until the 1850s.

But it's not a rare coin by most measurements of the word, sorry to say.

Just to thank you all for being so helpful and much appreciated.

Were the coin struck by Screw press or steam-powered machine?
Do the coin use modern planchet? (fully round planchet)
