Hi,
Right now, this “coin” is mentioned as Single material = aluminum.
I don't feel that's really accurate as I can see:
1 - a case in aluminum or tinplate
2 - a cover in mica or cellophane
3 - a stamp in paper
4 - Optional: a stamp back sheet in paper or cardboard
5 - Optional: a painted case
So at least 3 material and not 1 as we currently have…
