<p>[QUOTE=&quot;robinjojo, post: 4770957, member: 110226&quot;]The sand or soil patina looks good to me.&nbsp; Natural sand patina is very hard and impervious to acetone.&nbsp; Artificial sand patina applied with some bonding agent, such as glue, would dissolve in 100% acetone. </p><p><br /></p><p>Natural sand patina will soften, somewhat, if left in distilled water for several hours, but it is very tough, and any attempt to remove it, especially if it is thick, takes many steps.&nbsp; Also, the surface under the sand patina might actually be of a lighter shade compared to the exposed areas of the coin.&nbsp; This is especially true for bronze coins.[/QUOTE]</p><p><br /></p>
