<p>[QUOTE=&quot;Maxfli, post: 2830077, member: 69089&quot;]I give all raw coins a bath. I stated the reasons why in another thread today, so I won&#039;t repeat it here.

It seems to performs the same function, and like acetone, it&#039;s safe to use on coins.</p><p><br /></p><p><br /></p><p>I always start with water first, but I can&#039;t offer a scientifically based argument for it. Just seems like the right thing to do.</p><p><br /></p><p>This comment isn&#039;t necessarily directed at you, but there seems to be a lot of anxiety on this forum with regard to using acetone, and there shouldn&#039;t be. It doesn&#039;t react chemically with the metal in coins at all.&nbsp; All it does is loosen and help remove organic matter that may have accumulated on a coin&#039;s surface. I use acetone (or xylene) on every raw coin I buy, even UNC coins, because I don&#039;t know where the coin has been, how it&#039;s been stored, or what it may have been exposed to (including organic compounds that may not yet be visible to the naked eye).[/QUOTE]</p><p><br /></p>
