Check out this beautiful 1974 Switzerland Swiss Helvetica 20 Rappen coin. What I love about it is that you can see clear details both on the front and on the back of the coin. Check out the “Libertas” written on the crown of the head on the front of the coin. The detail is astonishing. This is a wonderful coin to add to your collection. This coin weighs 4 g and is produced out of a copper nickel alloy. They only made 30 million of these coins. A coin like this is worth about $4. If you have any questions about this coin, feel free to ask.
