<p>[QUOTE=&quot;desertgem, post: 501025, member: 15199&quot;]I think that Thads Verdigone is an excellent addition to conservation ( which I consider it) <b>when it is used as directed .</b> However neither it or acetone can <b>repair</b> the damage done and lurking beneath the surface gunk. Acetone is realtively cheap at Wal Mart and can dissolve most organic ( non annealed ) deposits. Verdigone will slowly and gradually remove most copper corrosion products, but not organic or annealed organic &quot;carbon spots&quot;. It is much more expensive due to its composition.&nbsp; The Man 12 might spend more on chemicals for the coin ( 1880 VF Numismedia&nbsp; $9) and still have an ugly corroded coin than buying a better appearing one. Carbon spots are still here to stay.</p><p><br /></p><p>&nbsp;&nbsp;&nbsp; If it was a more expensive coin or a lesser damaged one, that&nbsp; would be OK to try, but Verdigone solution is limited chemically by the amount of corrosion products it can remove and multiple changes of solution would be required to get a near end point and it is almost a certainty that there is serious damage beneath that green gunk.</p><p><br /></p><p>Put it aside and buy a nice one IMO.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
