welder Pillar of the Community United States 1037 Posts	Posted 08/27/2014 9:58 pm I have heard that Canadian SML's are notorious for milk spots. Some have said that the spots appear long after the coins have been minted and sold. My 2013 1.5oz Polar Bear is getting a big hazy spot on the obverse and I know it wasn't there the day I bought it. My question is regarding old US proof coins with milk spots. Did the coins come out of the Mint that way or did the milk spots develop on the coin over time? Thank you. Report this Post to the Staff

They dont often come from the mint with spots but develop over time, sealed or not dont seem to matter. Report this Post to the Staff
