How much is a 1968 20 cent fraternite in US money?

Answer 1

My guess is that if you looked more closely at the coin you'd see that the motto is "Liberté, Egalité, Fraternité", the denomination is centimes, not cents, AND the country is "République Française"

So, what you have is a low-denomination coin used in France prior to adoption of the euro in 2002. At that time, 20 cts was worth about 3¢ U.S.
