    Cyanide? Sounds a bit extreme lol is that what makes some of those silver coins that extremely bright white?

    Also I’m questioning that D now I asked for clearer pictures of the MM when he has a chance but it looks filled to me, I don’t know how common filled Ds were back then if at all? And it’s hard to make out if there are north or south serifs on the left side of the D which would mean it was most likely a 1932-P previously

    No ethics problem there, right. One you tarnish the coin, removing the "tone" removes part of the surface because the surface is chemically transformed. So you are likely doing even more damage to it.

    Acwetone can't remove anything but organic material the metal of the coin is safe and it is not going to help with a tanished coin, which is that the toning is....if it is real toning,

    Well cyanide is still used today ( mostly offshore ) to extract gold dust from crushed ore.But use in numismatics stopped for most after this news back in 1922.

    and less dangerous methods prevailed. I am in an area where alluvial gold is still mined, they use cyanide spray over crushed ore to leach leach1.JPG out the gold particles.

    I believe that to be chemically enhanced with a reagent not natural, he has told me that he does this to his coins. I may leave it as is if I do pick it up.

    That was a good read, sad mistake! I did not know cyanide played a part in the numismatic field or for separating gold, thank you for the share!

    I don't have experience with MS70 specifically but I think that's a particularly aggressive dip if I recall.

    RIP Mr. Saltus :eek:
    That’s an alternate spelling my great grandfather used because he didn’t know English. :woot:

    I was just looking at a post few days I go I think it was a gold coin. And it had grafitti on it. The buyer was aware so good thing he was happy with the price.

    Anyway

    I can't help but to look at the left of Washingtons nose & I swear I see multiple letters & #s.

    Sorry if my mind's playing tricks on me.
    Turn the coin side ways & infront of the nose is a 6 then slight lower to right a V & lower right of that a $ .25.

    I believe it was the moderator on the first page, he gave in depth details. I have some people saying acetone is fine and other say it’s not. If I do I’m go ahead and pick it up I may let it be just in case that chemical toner removes any luster it may be binded to. Im more interested in seeing a more clear picture of the MM before I move forward to see if it’s authentic or not.

    I see what your saying with the 6 lol good eyes! The other ones not so much maybe a 55? I’m concerned about the D as it looks filled and should not be, It looks like a square blob to me. Also I am not seeing the serifs that should be there also

    Not sure if it's the picture from exaggerating the toning, but yeah, that 6 or 9 in front of his nose is concerning also.

    It's not a dip, but for this application you can use it like one. Unlike dips which are strong acids, MS70 is a strong base.

    Yes I agree that is a good observation I did not catch that until mentioned, that could give it a scratched details. I wish his pictures weren’t so grainy. He said he will send more pictures but that was yesterday still nothing I will update if or when they come him.
