<p>[QUOTE="TheMont, post: 3056097, member: 80121"]I have used a product called MS70 on both Proof and Uncirculated coins and it has removed toning and gives the coin a nice natural looking luster. It should not be used on circulated coins, because it gives them an unnatural luster, I guess that's why it's called MS70, it's for coins that would grade 69 or 70. I've never tried it on a cent, so I'd use it on pocket change first to see how it reacts with the copper.</p><p>The bottle lists gold, silver, nickel, copper, bronze and brass. It doesn'the have any acid in it so it's not supposed to react with the coins metal, only the toning.[/QUOTE]</p><p><br /></p>
