Assuming you have a French coin (it'll have Republique Francaise on it), very little. At the time that France retired francs and centimes in favor of euros, your coin was worth around 4 cents.
The French 10 centimes coin from 1998 does not contain silver; it is made primarily of nickel and copper. Specifically, it is composed of 75% copper and 25% nickel. Silver was not used in the production of this denomination during that year. Thus, the coin has no intrinsic silver content.
Yes, I have one in my hand.
You are probably asking about a 1922 coin from the Belgian Congo ("Congo Belge" in French). There were three different denominations produced in 1922 - 10 centimes, 50 centimes and 1 franc. Assuming that your coin has some appreciable signs of wear, the coin is likely worth no more than a dollar or two.
50 centimes
The value of a 1964 French 20 centimes coin can vary depending on its condition, rarity, and demand among collectors. As of now, a circulated 1964 French 20 centimes coin may be worth around $0.50 to $2 USD. However, if the coin is in uncirculated condition or has any unique characteristics, it could potentially be valued higher by collectors or numismatists. I recommend consulting with a professional coin appraiser or checking recent auction results to get a more accurate valuation.
