Neutralizing Milk Spots on Silver Eagles....

Did someone say there was a way to do this!!!! I recall someone saying something about it...but I can not remember what?

I believe that if you give them a light dip followed with a thorough water rinse followed by a dip in either acetone or alcohol (NOT BEER and NOT SCOTCH!) that you can minimize the milk spotting on these coins.

I tried that remedy on a sms quarter to no avail.

It doesn't work if the spots have already developed. It's a preventative measure.

Nothing will remove them or neutralize them. This is a quality control issue at the mint. They're not drying the strips properly after they are washed/rinsed. They must me rotated and forced air dried. (my small brain thinking

)

Nothing will do so after they develop.

Of course, Russ.... the humidity factor ?

I know many develop afterward, and I often wondered if this was just because of "moisture" from the environment or a person's breath.

edit to ask: Is the acetone a measure to keep more spots from showing up ?

For those of you using this experimental technique, how long have these dipped coins remained spot-free?

I've been doing it with late 50's and early 60's proofs, which are also prone to developing milk spots, for over four years. None that I've kept in my stash have grown spots.

What causes milk spots and why don't silver rounds seem to harbor them?

silvereagleproof · December 5, 2006 11:44AM

Dip will remove some spotting on proofs, nothing removes them on uncirculated ones besides sand paper!

topstuf · December 6, 2006 3:30AM

Ah, I see.

If it is the white spots on the coins developed in the original mint packaging I have always beleived it is a solvent or oil drops on the planchet or die prior to being struck.
They are not removable, they can be reduced however there will always be an outline of disoloration.

sandblasting works well...

You can remove milk spots on any modern coinage with a dremel tool.

This is also a problem with 40% Silver Clad IKEs. I submitted one in July of this year and do not recall if I stabilized it but, that sucker has milk spots on it today. I know that I would not have submitted a milk spotted coin for grading!

Dang!

I have found a belt sander works well to!
