Acetone is not too late after vaseline.
macmercury, you nailed it. Pure Acetone bath is the final step and removes all oil from the surface. I didn't intend for this tread to be about conservation or would have explained step by step. This was an exercise in grading from poor seller photos. I figured someone would point out about the missing black grime on the in hand photos so told you something I have used to remove that for the last 60+ years.
Is there anyone here that believes the TPG Conservation Services ONLY use pure Acetone to conserve coins that are sent in and paid for their services?
Do I have to worry about a TPG giving this a 94 or 98 code? NO, it's a low grade cheap coin that would not justify the cost of slabbing, a hole filler that I feel I have improved the eye appeal on over what it looked like when I got it.
I've used only Acetone in the past with less success. Acetone tends to dry out the grime without loosening it. Acetone works great removing NOSE GREASE, glue, paint, lacquer, PVC and oils. Vaseline softens it and makes it easy to remove, followed by the pure Acetone bath to remove anything left on the surfaces.
