Milk spots are an artifact of the planchet washing process. As far as anyone knows, it's not possible to remove them without ruining the coin.

I'm with SuperDave, from all the reading I have done, there is nothing to remove the spots, besides melting the coin down

Sorry to say but milk spots are next to impossible to remove from Proof strike coins. I've been in the coin biz since 1954 and have seen (and done) some of the most horific attempts to clean coins throughout the years. It takes a long time for it to sink in that you usually end up worse than you started. I would try to return it if it wasn't advertised as "impaired" in some way. Just my humble old timers opinion.  |

So called Milk Spots can be different on coins. Some are from one thing and some from others. Some are now part of the coin and some just stains. Regardless, if you prize those coins, be carefull. you can acquire Acetone from almost any place that deals with paints. Do a search on this forum for methods and usages of Acetone. Now here is my Two Cents on removing those type of stains. I've found a few Mercury dimes some time back with what looked like Milk Spots. Since not really valuable ones I tried the following? Soaked in Distilled water for a few days. No results. Soaked in Acetone for a few days. No results. Soaked in Paint Thinner for a few days. No results. Soaked in Jewlery Cleaner from Walmart for a few days. The one that states "For Silver Only, do not emerse for more than 10 Seconds". No results. My next attempt will be baking soda and water solution. by now not much to loose. The dimes now look like they've been polished with auto polish. |

Thank you all for your comments!
I see that it is really hard to remove milk spots, but since I bought these at near spot, I will try with acetone first, and then MS70.
Will post results later... hope this works!

Well, acetone didn't work. I even tried to soak it in  Formula 409, but that seemed to sort of work. At least it didn't damage the color of the coin.  I think what has worked the most as of now is just leaving the tube open in my room. Some of the minor ones are gone, but I will try some more things before I post pics. Edited by wd1040

:) It's basically like a super detergent. It's like what you use to clean the oil-smoke-sucking machine (since you live in Singapore, you should know this machine!) |

Well, it blackened the pie dish I had it in, but as for the coin... not much... It's still shiny, and the spots are still there. I'm... going.... to .... just.... leave... them.... open and wait for silver to go back to ~$12, 13 so I can sell them... I know what not to buy again: silver maples... (for hairline-ability and possible milk spots). If I need silver bullion again, I'm going to buy American.  |
