They definitely look like the milk spots that the Canadian Silver Maples are known for. Google "milk spots" for info. You can make them go away--there's a video in YouTube on how to do that (which is good for info, even if you don't use the techniques presented). Many will debate the advisability of using those techniques (especially using a pencil eraser). I guess that call comes down to the value of the coin and how much you value the "original condition" of the coin.
Quote: They are milk spots. It has to do with something going wrong during the planchet washing process. Either a bad formula or they weren't properly dried.
I think more specifically the rinsing part of the process. Very common on maples.
Jewelry cloth works well for me, but the rubber eraser does more harm than good. It leaves the coin with a "oily or waxy" residue that's really hard to get off without using coin cleaning solutions (acid)."
