Help with slight differences

Can someone post a side by side picture of the two different .1939. French 10c. KM# 889.1 and 889.2. I have a few of these coins and I can't see any differance in the flanges.

On a related note for the admin: would it be possible to add side by side pictures to the coin pages for coins like this?  I have a severial coins in my collection that I am unsure of the listing, because there are minor differances.

A small picture, like the one used for the edge veiw would make a positive ID of varients much easier.

 That Topic was started on 9-May-2011 and in it the member  cobra  gave a link for his own site, which shows a lot of variances for all sorts of coins. The site mentioned is ...

 I had a quick look and did not see KM# 889 in the Europe / France section but maybe it can be added.

 I think KM# 889.1 is thicker than KM# 889.2
I think the flan is the blank coin before it is pressed, so it is the thickness
Most are the same i.e. the normal KM# 889.1 is what yours are, so I guess a thin KM# 889.2 is rarer.
Anyone have any answers, as I would like to know as well.
  And I agree about somewhere to point out what the differences are. I thought a while ago about a part on the coin page that is neither marked Obverse or Reverse but is called Notes (in it can be put such information that is not really relevant to either side). Meaning sometimes, for example, a note is in the Obverse section when it relates to the whole coin.  Then in Notes can also be added the small pictures to show the differences (or a link to a page that does show them - perhaps a separate section in Numisdoc). Though I did see Notes (well, mintmarks) mentioned in another Topic already ...

 It would be handy to have differences shown; as in a recent swap I accidentally put a Spanish coin for exchange in the line below where it should have been, and it was only when the other member received it did they kindly point out what the difference was.  
 And finally, I always wondered what  (fr) BE  means against some years on a coin page. I do know that the  (fr)  part means it is on the French version of the page, but what does  BE  mean please ? For no other reason than that just given, in that when entering a coin for exchange I don't want to put a quantity in the wrong box, again. Thanks  

Yes, it has been talked about before. I didn't know if it was in the works or if it was un-do-able.

Some coins have very, very small differences and a side-by-side comparison is the only way to be sure which one you have. The pictures on the link you posted are perfect. If we had a way to add them(or pictures of our own coins) on the coin page or as a link to individal coins, we could make a better identification of the coins we have in our collections as well as our swap list.

Just an idea..

Thin flan 1.35/1.45mm. Thick flan 1.50mm
