Just about all of Swiss 5, 10, and 20 rappen coins are minted in copper nickel. The one in our picture is special ~~ it is minted in brass. Copper nickel coins are lighter in color, but the pattern is the same. Some coins were also minted in aluminum brass, which takes on a golden color.

These long-running series have a few special dates, but most are worth less than $1 US dollar in average circulated condition. Here is a run-down on these three coin series. Values shown are for coins in well preserved condition, like our picture. If your coin is not a nice as the picture, it will be worth substantially less. If your coin is fully, absoluately uncirculated, then it will be worth about twice these values:

You don't see fully uncirculated coins very much. They are, by definition, in someone's coin collection. Otherwise they would be circulated. Also, you must use our Important Terminology page to undertsand what the 'catalog values' quote above mean.

About 'Helvetica' from Wikipedia: The area occupied by the Helvetii, the namesakes of the later Confoederatio Helvetica, first became part of Rome's Gallia Belgica province and then of its Germania Superior province, while the eastern portion of modern Switzerland was integrated into the Roman province of Raetia.
