How much is a 1929 confoederatio helvetica?

Answer 1

"Confoederatio Helvetica" is the Latin name for Switzerland (because Swiss citizens speak 4 different languages, they use Latin on the coins so as to be fair to everyone), but without knowing the denomination (value) of the coin it's like asking "how much is a 1929 U.S.A. ?".

If the number on the reverse (back) is followed by 'Fr.' then it is a 1-Franc, half-Franc, or 2-Franc. These are all 0.835 *real silver* (i.e. 83.5% silver) - the 1 Franc has 0.1342 of an ounce of silver in it (the 2-Franc has twice as much, a half-Franc, half as much - simple !). To find out how much an ounce of silver is worth right now, try looking at www.kitco.com or www.24hgold.com. Then use a calculator.

If the number on the reverse has no letters after it, it's basically a number of 'cents' (called a 'Rappen' in German, 'centime' in French, 'centesimo' in Italian, or 'rap' in Romansh). You probably couldn't sell it unless it's totally unscratched and shiny ('brilliant uncirculated', or BU) - but if it is, look it up on the related link.
