But it will take an EF/AU coin and make it look shiny so unsuspecting buyers will pay more for it. </p><p><br /></p><p>If you don&#039;t believe me, take a look at this Lincoln cent which I polished with baking soda, as described. It has the exact same shiny look with a halo around the devices. I recommend that anyone interested take a low value, modern coin out of their pocket change and try it! </p><p><br /></p><p>[ATTACH=full]725831[/ATTACH][/QUOTE]</p><p><br /></p>
