<p>[QUOTE="Harryj, post: 497793, member: 14623"]Once the original brown patina is removed not much is going to bring it back beyond years of toning. Sulfer powder mixed with vaseline can turn it too black. Many people mess with cleaned coins and end up making them look even worse than when they started. You could try placing it on piece of oak plank and place it on your windowsill, however the sun tends to tone the high recesses of the coin more than the lower recesses. The area around the lettering will still be lighter than the rest of the coin. I've heard of people using the oak block/sun method with a piece of tissue with crushed matchheads in it, covered by a glass or shotglass but never tried it. Some people have even been known "bake" pennies in an oven. To my knowledge nothing but time will return the natural patina, and even then experts will still be able to detect the coin was cleaned.</p><p> </p><p>I have an example of a cleaned IHC that was retoned in the sun on an oak plank. It may have made it look a little better but it still looks cleaned. I'll try to post a pic tomorrow.[/QUOTE]</p><p><br /></p>
