In 1977 francs were used by several European countries, but all of those coins were made of copper-nickel rather than silver and have no extra value.
If it's from France (République Française) or Belgium (Belgie) it's no longer in circulation and has curiosity value only.
If it's from Switzerland (Helvetica) it's still in use and is worth a bit less than US$1 as of mid-2010.
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.
No
Face value only, unless it's a proof coin in its original holder. Retail for that coin is about $4. Face value only. It's made of copper-nickel, not silver. You must be in possession of an Eisenhower Dollar - a coin that was minted in 1977 that is in a mint state of MS63, is worth: $5.00.
