<p>[QUOTE=&quot;Theodosius, post: 2658474, member: 77077&quot;]When a bronze coin has a patina so thick it obscures the design (or when it is coated with thick dirt or gunk) sometimes the outer layers can be removed using a soft brass brush or fiberglass pen (use with proper safety gear).&nbsp; This can leave the pits and low spots filled in with patina while exposing more of the details. This is an alternative to chemicals which are harder to control how much they will remove.&nbsp; People sometimes have success with dabbing chemicals on specific areas with a q tip.&nbsp; The more I do this the more I like mechanical cleaning versus chemicals but every ancient coin is different. </p><p><br /></p><p>I appreciate you sharing this with us.[/QUOTE]</p><p><br /></p>
