Very little. Francs were the currency of France until adoption of the euro in 2002. Before they were removed from circulation a lot were hoarded by collectors. At the exchange rate in effect in 2002, one franc was worth about 22 cents.
These were ordinary circulation coins up till the euro was adopted in 2002. If they are just from pocket change they're only worth face value, about 20 cents per franc at the time of euro conversion.
More information is needed because several countries used francs as their currency in 1970. Please post a new, separate question with the coin's country of origin. (Belgie = Belgium, Confoederatio Helvetica = Switzerland)
In order to determine the exact value of a 1976 1 franc coin a few different factors would need to be considered. Most importantly, the condition of the coin.
This was a common circulation coin until France adopted the euro in 2002. At that time it was worth about 15 cents.
Assuming the coin is from France, it was a common circulation coin until adoption of the euro in 2002. At that time it was worth roughly 20 US cents.
About 20 cents.
A 1969 1 Franc coin is worth about $0.22.

The value of a 1924 1 Franc depends on the condition of the coin. A worn coin is valued at less than a dollar while a fully uncirculated coin is valued at 5 US dollars.
You need to be more specific. First, what country are we talking about? Many countries have (or had) currencies known as the Franc. Secondly, if this is a coin, you need to provide the year and an estimate of condition (for example, a 1843 French 1 Franc coin that is well-worn).
"Helvetia" is the national name for the country we call Switzerland. You have a standard circulation coin worth face value. At current exchange rates 1 Swiss franc is worth about 83¢ U.S.
The year on the Swiss Franc coin says nothing about the value but about the date when the coin was fabricated. Check out the number on the coin to see how much it's worth. You have the smallest piece (5 Rappen) going up to pieces of 10, 20 and 50 Rappen (100 Rappen = 1 Franc) , 1, 2 and 5 Swiss Franc coins.
There is a big difference in value between the France Franc and the Belgium Franc, so please specify.
No. Copper-nickel. These circulated regularly until France adopted the euro in 2002. If your coin is from circulation it's worth less than a quarter. Correction: French francs from 1960-2000 are .999 nickel and as of 8/8/2012, nickel is trading at just over double the price of copper per pound, of which a U.S. quarter is made, so the melt value of a 1960 franc is over double the value of a quarter.

Absolutely nothing at all. The franc is no longer in use, and there are many, many thousands still kicking around the world. Maybe in a thousand years it will have value, but there's no guarantee even of that.
In order to give an accurate estimate of value, the full denomination of the coin must be known. Please examine this coin and then submit a new question with the required information.
