I call this design elegant. I like it. Some people, I'm sure, would dismiss it as too simple.
These coins are made of chrome plated stainless steel. The 5 centimes denomination ran only from 1961 to 1964, but the 1 centime ran all the way to 2001, when Euro coinage took over in France. Then, in 2000 and 2001, France issued 1 centime coins in gold. Those are worth a lot more than 1 centime.
1 CENTIME AND 5 CENTIMES
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
well preserved: less than $1
fully uncirculated: $1
Coins dated after 1986 did not enter circulation and were sold only in sets. These are worth a tad more, $2 fully uncirculated.
The gold centimes contain 0.0603 troy ounces of gold. They are worth their gold value (look it up), plus a few more dollars if in superb condition.
