Hi, I have two french 5 francs Coins. I would like to know their value, silver content, and whether or not I should clean them.
Please upload photos of them.
Also, for coins around then (1800-2017), cleaning them would make them drop near their metal value, typically reduces its value to around 50-70% less then when it is uncleaned.
I strongly discourage and advice against cleaning those coins, unless they are Ancient or Medieval coins, before 1700s, and even then, cleaning should be determined on the condition the coin is in.
For your French 5 Francs, cleaning them would have it loose nearly all its worth.
are your coins on our 'France' page? See here:
