token

Help to identify a bimetallic token.If the possible added to catalogue

So, the tokens are definitely German - the single-side reads as “Germany: Unity and Justice and Freedom”, which is the unofficial national motto.

Tokens are:

Celebrating Heinrich Boll for winning the Nobel Prize for Literature in 1972

Celebrating the first Federal President of West Germany; Heuss

Celebrating the first Chancellor of West Germany; Adenhauer

Celebrating(?) the first constructive vote of no confidence. I don't know much about this, but a quick google states that the first one in West Germany was in 1972 in where the Chancellor (Willy Brandt) very narrowly survived the political vote.

As far as I can tell, none of them are in the catalogue - I searched the nation of “Germany” and then filtered using composition “Bimetallic”. There are a few tourist tokens which look similar in style, but none are exact matches for your four - which isn't surprising for the exonumia catalogue. It's a very niche field, and there's a lot of exonumia produced.

over here,  we have subscriptions for such series of memorabilia, educational, or historic. could be famous men presidents, airplanes, or events, on coins like this, or silver ingots, or stamps on envelops, or what not. Grannies sign up for their young'ns birthdays or such, and they come for a while, and then it seems you have to pay for any more, and its over, and you have six out of 50 in the series. and you leave them in a drawer for 30 years.

These looks like that kind of series but I don't know if Germany ever had such fal-di-ral.

Edit to add: I read all Heinrich Böll's novels back then. Amazingly engaging story teller.
