  • no.

    How do you know that since you can't remove them?

    my point was that you can never remove the spot AND the etched surface underneath the spot. i`m sure there is a dip that would remove the spot but now you have a dipped POS. i`ve heard you can dip before the spots actually show up and eliminate them.

    I believe that if you dip before the spots become visible that they will indeed be prevented from forming. Not 100% sure that removing them will leave an etched spot, but its likely that it will. The one person that claimed to have found a remedy, couldn't do it well enough to get the coins back into a holder.

    I've had no luck with acetone removing spots.
    From what I've heard, the spot was on the planchet before striking.
    When struck, the spot becomes impressed into the coin, becoming part of the coin.
    Good luck,

  • PCGS was offering a $50K reward a few years ago for anyone who had a method/formula for removal of milk spots on ASE's (if I remember correctly)

    No one collected the reward... they will appear after time on some coins. They cannot be removed. An acetone soak prior to appearance, followed by an alcohol rinse and DI wash will prevent most spots from appearing. Many ASE's never develop milk spots. Cheers, RickO

    Ricko, in your opinion, do you think the milk spots are post minting or something that got on them during rinse or machine chems after minting.. Someone told me once, during smelting something got into the silver during final cooling and thus it appears at a later time.. Just looking for theories..

    I believe that a dip like E Zest is required to remove the material responsible for spotting.

    Its been said that you can see the spots before they become visible to the eye by shining light from a halogen flashlight onto them.

    The round appearance of the spots suggests that their origin is water borne.

    Examination thru a high resolution microscope shows that they form on the rough surfaces of the coin. My limited examination of one spotted coin suggests that the principal component of the spots is chlorine. I think the planchets are washed with bleach [the hypochlorous acid form and not the sodium hypochlorite version].

    The spots can't be removed with sodium cyanide or sodium thiosulfate solutions.

    A scanning electron micrograph aka a pic from an SEM scanning electron microscope is shown too.

  • I have heard a theory that it has to do with a rinse of planchet pre-striking, and spots on some ASE's will appear, just a matter of time



    and even dipping will not help, similar to carbon spots in gold due to alloy mixing

    It is more likely due to the failure to remove the rinse agent or lousy final washing of the planchets with pure water.
