I have looked through the listings and cannot find any silver 5 franc pieces issued by the Republic of France in 1946. In that year 5 franc pieces were issued in both Aluminum-bronxe and Aluminum. I am assuming that you have an Aluminum issue. These coins were minted at three mints: Paris(no mint mark), Beaumont (B) and Castelsarrasin (C). Value for the first two mints is fairly low, from fifty cents in Fine condition to $3USD in Extremely Fine. Mintages at Castelsarrasin was fairly low, and values range from $8USD in Fine to $38USD in Extremely FIne condition.
There is no 29 Franc gold coin. If you mean 20 francs it is worth about $250.
In 1977, the French used the franc. A 1977 50 francs coin is worth just under 15 US dollars. The silver content of the coin is worth 11 US dollars alone.
If it's bronze, 10-20$. Just a regular silver coin, maybe 3$ if your lucky.
Check that coin again. The U.S. didn't mint any silver dollars in the 1940s.
A 1968 Confoederatio Helvetica coin 5 francs is worth between 5 and 20 US dollars. The value depends on the condition of the coin.
About 45¢.
Check that coin again. There were no US silver dollars minted that year, or even that decade.
10 dollars
1946 is a common date, currently worth about $2 for the silver. JS stands for John Sinnock, the Mint engraver who designed the coin.
copper-nickel and its worth 2.00$
The U.S. never minted a silver penny. For starters, it would be worth more than a dime! Your coin was plated for use in jewelry or something similar. That makes it an altered coin worth face value only.
The amount of silver in French coins, specifically the old Francs, varied depending on the type and period of the coin. For example, the 5-franc coin from the 19th century typically contained 0.900 (90%) silver, which equates to approximately 0.7234 troy ounces of silver. However, modern French Francs (post-1960) are no longer made of silver and are instead composed of other metals. For specific values, it's important to check the current market price of silver and the coin's weight.
