Thanks for your advices, guys.
Jaobler, you seem really knowledgeable about these kinds of coin. Indeed my two coins are both copper/silver, and although they can separate, it's not the same system as the one you've shown.
Anyway, I will try these methods and let you know what happen. But I think I may end up buying new gimmicked coins (the two coins in the above picture are $50 each......). Because at that moment now they are unusable for my show, unless they look exactly like my other normal half dollar and english penny coins.
I can just tell you now that the washing with warm water and soap doesn't work. Will try some of the products you guys mentioned. Next time, I will be careful before tempting anything that stupid; I would have never guessed that these coins could have such reactions to barbecue sauce, or anything like this.
