Hello all,
Recently, I posted some shots of my 1910 quarter eagle, which had a green accumulation on the headdress and eagle's feathers, possibly from PVC, or some other form of environmental damage. Having read other's experiences, I decided to try my hand at cleaning the coin. For my first try at this, I worked in a lab environment. For the active cleaning agent, I used histological grade acetone; for the wash, I used de-ionized water. I poured the acetone into two labeled containers, and the h20 in a third. Using non-latex gloves, I placed the coin in acetone bath one for approximately sixty seconds. Periodically, I gently sifted the container, taking pains to ensure that the coin remained stationary, and only the fluid moved. After a minute, I lifted the coin out and placed it in the second acetone bath, and repeated the steps above. Finally, I placed the coin in the water bath and let sit. After a minute or so, I poured the contents onto several sheets of microscope lens paper, which caught the coin, while allowing the water to pass. Using a squeeze bottle, I gently doused both sides of the coins with more de-ionized water. Finally, I lightly dabbed the coin with several more sheets of lens paper before letting it air dry on a lens cloth. Below are the before pictures, followed by the afters. I'm planning on sending it to PCGS for grading. Any opinions on what it might garner? Thanks!
