Hi Carmen -- These coins have been minted since 1962 in aluminum bronze, not gold (shucks!). As such, they are worth face value. There are 100 centimes in a franc, so the 10 centimes is worth one-tenth franc and the 5 centimes is worth one-twentieth franc. Use XE.com to do exchange rate calculations.
