<p>[QUOTE=&quot;medoraman, post: 1625795, member: 26302&quot;]I would differentiate though between these patinas and &quot;sandy&quot; patina. A sandy patina is really only dirt still on the coin, with the resulting highlighting of the coin sticking through resulting in a pleasant appearance. Black and hard green patinas are a rare chemical reaction that changes the color of the underlying metal to a plasant color. </p><p><br /></p><p>While I like all of them, to me there is just inherent differences. A sandy patina is in theory reproducible, if you get the coin dirty again and just brush off the higher points. Black and hard green aren&#039;t reproducible, (though some do try with paints). Painted patina IS a concern with these. I may look like an idiot, but I actually sniff patina like this, then look at it under a higher power magnifier, (I use my 16/32x stereo microscope), to ensure its a true patina, and not paint.[/QUOTE]</p><p><br /></p>
