mdpmedia Pillar of the Community United States 3546 Posts	Posted 09/04/2024 8:27 pm About between 10 and 11 o'clock on the obverse I was able to scrape off a lot of that cake on crud. But I did not continue it since I did not know how much more value it would bring doing that. I just want to know if this type of very dark surface is considered environmental damage or natural toning, which would not detail the coin? Report this Post to the Staff

mdpmedia Pillar of the Community United States 3546 Posts	Posted 09/04/2024 10:10 pm I ran a Q-tip soaked in acetone over both sides and much of that flaky looking material from the first photos fell off. Are there any suggestions on what other type of substance I could use to remove that residue assuming it would improve the grade? Report this Post to the Staff

Greasy Fingers Pillar of the Community United States 7021 Posts	Posted 09/05/2024 12:31 am Since it's already damaged (environmental) I'd give it a long soak in acetone and then nose oil it, If the rough surface of the reverse doesn't come off with a soak....could it be concrete residue ? (kinda looks like it from my chair) I would never use acetone with a q-tip....just soak and rinse with h2o. Edited by Greasy Fingers 09/05/2024 12:32 am Report this Post to the Staff

DOCC Pillar of the Community United States 1502 Posts	Posted 09/05/2024 07:52 am Dirt coin !!! I've seen this type of build-up an untold number of times on metal detecting finds - it can be stubborn. Give it a soak in food-grade mineral oil for a week - rotate once a day. Pat dry and then Acetone for 24hrs to dry it out. That should create some air gaps in the crud. If you have a steady hand, wetted toothpick test on inconspicuous spot to see if you get any lift/removal. If you do, give it a round of VC and then Q-tip roll on the VC to lift. Sodium Sesquicarbonate would surely remove but could also expose more of the copper at the same time. I swing a metal detector and have a knack for finding dirty old coins.
