1971 French Franc- looks different?

I was going through my collection and I happened to notice that I had a 1971 Franc which looked different in that there was a circle around the woman at the back. I managed to find another 1971 franc which had no such circle, and I looked at pictures of 1971 francs online- none of them having the circle. The front of both of the 1971 francs were exactly the same.

All the francs from other dates (of that design at least) also had the default reverse.

Here's a picture- different one on the left (sorry about the quality, my phone's camera is terrible)

Does this mean anything?
Thanks

There seem to be a few discrepencies between the coin although its hard to say for sure as the picture is vey low quality.

Yeah, I know.
Here are two better pictures, sadly this is the best my phone is capable of at the moment.

I use a jewellers loop to get a better quality close up. Im torn between saying error coin and fake. To help clear this up, does the coin in questionhave the sun and light beams in the backround behind the lady? Because i cant see it, just may not be vissable in the picture so i though i would ask.

Yes it has rays and a sun in the background, just like the normal coin.

Thatscool, just couldnt make them out in the pic, in that case from my experience i would say that is an error coin. Cant quite figure out how it happened but im less incline to say its a fake now. However maybe wait for a second oppinion from another fellow member of the site.

I have seen such circular damages on other coins. There it was damage made when closing the paper roll. If the machine is not set correct these things can happen.
Here is a belgian 10fr 1970:

Cool, was wondering how this may happen, so i guess this would not be classed as an error and rather after mint dammage? (Just sucking in all that knowlege your all have)

  There was a post on here a while ago where someone else had one, and I also added my pictures of one I had. I think it is caused by a faulty coin-sorting machine, where it is gouged while inside.  Also have seen similar marks on coins in which the country issues their coins in rolls, and the coin either end of the roll gets damaged by the paper turning machine.

EDIT: I found the topic, and my reply below it ...

here is a picture of a coin roll where this kind of damage can occur:

That's pretty interesting. So is this coin potentially worth anything or should I just keep it?

Considering you could do it yourself to the coin, unlike a misprint, I'd say it's actually devalued it... Would need a pro's opinion of course.

Wait wait, in Petrus' picture, it's not at all damage! Euro coins are MEANT to look like that.

So basically what happened is it was struck normally, but then got damaged as it was put in a roll?

the picture I posted is to show the kind of roll, not the contents

It's not an error, just common PMD. Coins from all countries have this damage

Bummer. Thanks for clearing that up, though.
