I know the other two very well...top right, 1/2 Swiss Frank KM# 23a1. That year is cupro-nickel. The other is 5 Swiss Rappen, Al-brass, KM#26c, It appears to be 1981 or more recent. The reverse of both coins says Confoederatio Helvetia, which confuses a lot of people! (Helveticum was the old Roman name for the region, and Helvetii was the general people group)
