Diameter is almost the same as in the catalogue, mine 21mm vs catalogue 20.5mm. Weight is also cloose, mine 1.8gr vs catalogue 19.5
I also noticed that the lettrering is not exactly in the same place as in the photo in our catalogue, specially in the portait side. Apart from that, lettrering is the same as in our example.
Last thing, the portait has some "extra hair" in his chest that does not exist in our example.

Any thoughts?
