2 Sous, Frenchcolony Cayenne 1789A

Thanks for your kind reply.
The three coins are actually part of a 12 coin group. I'm making a study of them with measurements and pictures.
There are 2 genuine, 2 contemporary and 2 imitations. I have not yet determined exactly what the remaining 6 pieces are.

Actually the mint director's privy mark at top is a Heron, but yes it is interesting how the counterfeiters each had their own idea. When you study the entire 12 coin group there are many differences among the crowns, lilies, dates, legends and so on. They are all photographed and documented in the book I'm making after accumulating counterfeit coins for well over 13 years.

Thank you for the tip. As a matter of fact, I just got a Charles Davis book yesterday. Looks like I need another one.

Would Albert or anyone else be able to tell me a reliable way to identify an authentic 1782 Cayenne 2 sous by checking something on the obverse or reverse? Judging from Albert's starting post in this thread the thickness of the coin is probably a reliable way, but unfortunately you rarely see an ebay listing where they show the edge of the coin. Any tips would be appreciated. Thanks.

Thank you Albert for replying. Right now on ebay there's a seller called "numis-kimel" who has about a dozen 1782 Cayenne coins for sale. If you can tell genuine from counterfeit at a glance then it would be great if you could point me the right way, but I don't want to make you spend a lot of time -- I can always just keep comparing whatever comes up on ebay to your picture at the top of this thread until I find a spot-on match. I've actually done this comparison with all these numis-kimel items already and none looks like a match to me, but you're the expert.

Thanks again Albert. My sense is that you are correct about sellers -- they most likely can't tell genuine from counterfeit, and they probably don't really care. That's why I'm not bothering to ask numis-kimel a bunch of questions -- he's selling so many coins, my sense is that he won't want to go back and forth with me.
The two items I'm looking at are 282565825481 and 272763630950. To me they look very similar to each other, but they don't really look like your genuine example -- most notably, the three fleur de lys on the coin look "off". On your genuine example the arms of the fleur de lys point a little bit out to the side and the tails are sort of rounded and elongated. While on this guy's two coins, the arms point straight down, and the tails are fatter and more diamond-shaped. But I'd definitely be interested in your opinion if you don't mind. Thanks.

OK here goes:
I feel better about the first than the second.
Not having weight, measures and density values doesn't help.
I began with a few coins that were hard to pin down, so I bought more coins that were identified for me.
This helped a little, but I found some sellers were mistaken.
At that time I had 6 coins that I knew and 6 I wasn't sure about.
So I bought more and more coins to study in the shop using the equipment.
That resulted in having 12 coins I knew and the other 12 uncertain.
I can't say for sure, but I can say the first one looks most like one of the genuine types.
I'm not too keen on the color as it looks more brassy than billon.
Maybe you could ask the seller for a good weight measure- that might help.
If it looks good AND has good weight then you could feel better about buying it.
The genuine coins I have all tend to be the heavier pieces.
I will also say that just looking at Cayenne 2 sous images can sometimes be a very poor way to say if a coin is official or not.
