<p>[QUOTE=&quot;Boss, post: 590067, member: 15110&quot;]Thanks guys- Frank- I actually did everything you said exactly, except mostly used mineral oil, and any rinsing was with acetone and then DW.&nbsp; I hurt the coin when I soaked it x about 2 days in acetone and this removed the old oils and showed hidden hairlines.&nbsp; The next mistake occurred with the contaminated dellars (not mixed the way Jim described).&nbsp; I didn&#039;t know you should mix dellars this way and had used undiluted many times on lower value coins without problems.&nbsp; This new Dellars I bought was coagulated (I inspected it after one new spot broke out).&nbsp; I soaked in acetone to (the main and big mistake here) removed verdigris.&nbsp; This showed the hairlines.&nbsp; The verdigris (3 spots on the rev) and the one new spot were removed via Verdigone and NCS.&nbsp; &nbsp; &nbsp;&nbsp; However, the coagulated Dellars also caused the grey toning.&nbsp; I sent to NCS to get this removed.&nbsp; &nbsp; &nbsp; I post all this for others benefit so they will learn, at risk to my own reputation.&nbsp; I figure if I can help others by my mistakes they will learn.&nbsp; Others can feel free to refernces these posts to those trying to clean high value coins with limited knowledge.&nbsp; &nbsp;&nbsp; Spocks idea is risky for me.&nbsp; I will sell on eBay or keep.&nbsp; I have lost so much money on coins due to mistakes (thousands) I can&#039;t afford any more losses.&nbsp; Wouldn&#039;t suprise me if I got more than $1,100 for this coin on eBay.[/QUOTE]</p><p><br /></p>
