Hi again,
Sorry for my short silence but I was left for aprox one hour.
Pekka, I am very sorry for the confusion I
had created, because in my first post I mentioned 10 mm diam, but it is 20 mm; I have wrote by mistake 10 mm.
The coin has 20 mm and the
weight is 1.26 g; the composition is billion.
Sorry again for the mistake I've done in my first message and thank you all again for your
help.
Regards,
alc
