Just FYI, it looks like the OP did post about this over on the French forum first:

The OP states over on the French forums that he/she still can't locate the coin (despite the help they provided). I'm just conveying this to eliminate needless duplication of work. It would be helpful if the OP had stated here that they had already posted on the French side first.
