Once again you have posted a picture which, by it's darkness, conceals a key design feature. Your 5 centime French copper is either: KM#797.1, Paris Mint, with an "A" mint mark, mintage 12,128,000, $3-6 KM#797.2, Strasbourg Mint, with a "BB" mint mark, mintage , 2,323,000, $20-40 KM#797.3, Bordeaux Mint, with a "K" mintmark, mintage 9,437,000, $3-8. All valuations are catalog value from the 2001 3rd Ed. 19th Century Krause for F to VF.
I will work on improving the pics. These coins are sometimes hard to work with, but I will learn to work around that.
