<p>[QUOTE="Just Carl, post: 229863, member: 4552"]Nothing beats leaving well enough alone though. Any cleaning with any brush will leave lines detectible by any grading services today and flag the coin as cleaned or harshly cleaned. Doing this is similar to taking a 500 year old table and sanding it down and then painting it with Walmart paint spray cans. Nice dark green of course. </p><p>OLIVE OIL? Not really smart either. Olive Oils are produced slightly different by different manufacturers and thererfore none are exactly the same. Some contain acids, others contain slight contaminates, many contain a variety of fats of different types. READ THE LABLES. Such products left on coins will do as much good for the coins as a fingerprint left by an auto mechanic after chaging someones oil. </p><p>Always note that removal of anything on a coin may now be part of the coin due to chemical compouding or just reactions. Unless you know what you are doing it is always best to leave old items of any kind alone.[/QUOTE]</p><p><br /></p>
