The medal edge and helmet was originally covered with a wash to depict the snow of that first Russian winter of 1941. This wash usually wears and the base zinc medal colour shows. Difficult to say if this one is real or not, but they are quite common. The suspension ring may be marked with a number. The ribbon is a new one of course.

I agree with the comments above and certainly with the point about better pictures. This one looks OK but can't be 100% with these pictures.
Also, please upload pictures to the forum and not via an image hosting site. By uploading to the forum the pictures will remain permanent. If you use a host they will eventually disappear then the person who wants to look back at threads for reference will see only text and no pictures which is not much use at all. Try looking back, find a thread like that and you will see how frustrating it can be.
