<p>[QUOTE="Kevin Mader, post: 3952835, member: 106826"]Keep in mind that there are a number of mint state coins from decades past that look as good as the day they were minted. Preserved in state. And as noted, there was a time when cleaning coins was in vogue (perhaps 100 years ago); cleaned for display (usually just the obverse). But some folks will clean a coin to give it the appearance of a mint state coin. However, most collectors will spot a cleaned coin and avoid it...unless it's a rare/key coin that might be a step coin (i.e., a placeholder until a better specimen can be had). </p><p><br /></p><p>Coin conservation might be thought of as cleaning, but the intent is different. For example, a recovered coin from the deep might be encrusted with organic matter (e.g., coral) and must be removed to reveal what the object/coin is. A conservation usually requires a step process to remove the unwanted to reveal the object. It's not an attempt to make the old new again; it's a technique to restore an object to a desired state. With more common coins, conservation might be taken to stop verdigris, the green matter that plagues copper/bronze objects. The coin surface might be further compromised otherwise. So the hope is to stop the growth by removing it. This may enhance...or ruin a coins presentation (while conserving it). Normally, it's a problem coin at that point, but leaving it alone renders it a doomed coin anyway. So knowing what you have and what you want to do with it should be considered before taking a step that can't be undone. I suspect many botched attempts find their way to the 'Bay and are sold off; buyer beware.[/QUOTE]</p><p><br /></p>
