 That is the website of a member here. There are pictures of the varieties for that coin on that page. On other pages there are many varieties for many coins from around the world.  

  Thank you it was a great help, now I understand the difference, greetings!

Hello,

Yes, a great page. I also had problem with these coins.
Can we add these kind of pages to Numisdoc?
The same with some australian coins. The blunt wiskers.

After you looked at the French page, did you go to the Australia page on the same site? There are whiskers images on there, in the decimal section ...
