I know of no way to do it without destroying the coins surfaces.

Hi littlejohn:

I would generally answer "no," but a a few months ago I had a proof 68DCAM coin with spots.
I soaked it in acetone extensively. Not just a few hours, but 24 hours. Figured I didn't have much to lose.
I'd soak it, rinse it, soak it, rinse it, and did so for at least a day over a weekend.
I was surprised that the spots disappeared. Coin really cleaned up.
Sent the coin off, and it came back 69DCAM.

RR,

Were they the true milk spots???

What type of container did you use???

How many rinses did you do. You may be on to something!

Hi segoja:

Yep, they sure looked like milk spots on the proof.

I wanted to see what would happen if I soaked it for an extended period, so I let it soak all day one Saturday while I was out bush hogging. I'd let it sit for 4-5 hours in a container of acetone, come in and rinse it, let it dry for a few minutes, check it, then put it back in the acetone.

Did this a couple or three times during the day and saw no change. Then at the end day when I came in and checked it that evening, that's when I started to notice a change. I was surprised that the spots started to disappear. Got my loupe out, checked it, and scratched my head. Went to bed that night and left it in the acetone all night. Pulled it out the next morning, rinsed it, looked good, no spots, checked it with my loupe, scratched my head some more, packaged it up that Sunday and off to PCGS on Monday.

Like I said in the previous email, though, my answer is generally "no" to the initial question about removing spots from proof coins. I just wanted to offer up this example of what happened, for whatever it might be worth.

What causes "milk spots"?

braddick

Planchet washing from the Mint. (Peace dollars and Contemporary proof Franklins are two prime examples of series prone to having them.) Generally milk spots become etched into the planchet/coin during the minting process and getting them off is impossible without severe damage being performed to the coin.
The good news is some "milk spots" truly are not and a curration is appropriate.

I am ashamed to admit that when I was a young teen that I thought milk spots came from drinking milk and accidentally dribbling over proof coins.

Don't even ask about chocolate milk.

Russ

RR,

It is unlikely they were milk spots as milk spots are normally defined - ie mint made and embedded in the planchet. I've tried every conceivable approach to these, including precisely what you just outlined. Even NCS hasn't come up with a way to remove them.

I have some JFK proofs w/a light haze.

One word "Jewel-Luster"

segoja

Jewel Luster won;t budge true milk spots!

Simple toning and other minor disturbances yes, but not milk spots.

littlejohn

thank you all , very much,for all the info.

No.

Sorry to bump such an old thread, but it seems some people are suggesting acetone will remove the milk spots from ASEs, when in fact I believe it does not, it just protects them pre-spotting. I spent all night with several glass jars and a milk spotted eagle, with chemicals I think it would be illegal for me to leave my home with. I think more spots developed in trying to remove them than there were before I started. It is time for a milk spot melting party, in a big pot they all go. I'm going to mint myself a milkspot bar
