That's a really nice coin. I'm a little concerned with the green deposits. From your picture it looks flaky like bronze disease. This would indicate that the coin might be a fouree and some of the copper core is leaching. Looking at the coin it doesn't appear to be a fouree IMO. It's however strange to see the deposits in just that one area. It's possible that the coin might have been in contact with a bronze coin with BD, and some transferred over the your coin. In any event you should remove the deposits.

thanks all how can I remove the diese ASE

Thanks/ clean now
