Unclear remark in French telephone token

In the year distribution of the token
https://en.numista.com/catalogue/pieces36010.html

there are remarks: Frappe à 3h, Frappe à 6h, Frappe à 9h
Do they mean the dies alignment? If yes, then in which way?

By the way, the item, that looks like attributed by this article,
http://www.delcampe.net/page/item/id,0375825362,language,E.html
has mass 4.23 g. Though in the catalog the mass is 3.3 g which is smaller then for the similar zinc token https://en.numista.com/catalogue/pieces16650.html (5 g)

Can we check and verify/correct these data?

Yes they are dies alignment. However there is no mention about in which way this dies alignment is decided. I only know it's referring about position in clocks, or like for aerial fights.

Concerning weight, I've no idea.

Hello.
When you return the chip on its axis.This is explained on my website.

the strike has 6 hours does not exist.

Excellent!

So just a question with mass left and we will make the suggestions for catalog improvement.

We have in catalog:
zinc 5 g
this copper-nickel 3.3 g

verification:
this copper nickel dies alignment 3h has 4.2 g (http://www.delcampe.net/page/item/id,0375825362,language,E.html)

It means that we have to check both types.
