5 werth marke year determination

I've found the token on this website it has a high rarity number and I was wondering what year it was from as the website doesn't say

A high rarity index does not mean it is rare.
It just indicates that few members have this token.
Date? Somewhere between 1915 and 1930.
If you do a search for such tokens, you will find the same, but with names struck on it.
It is a general token that was used in vending, stores...
