Any new info on removing milk spots? I was looking at my 1.5 oz Canada polar bear coin yesterday and it has developed some spots. They were not there when I bought it. It sounds like I'm stuck with it. I wouldn't mind so much if it was on the queen side but it's on the bear side.

 

Are you sure which side is which : - )

 

Did you ever try it?

 

No. I don't have any myself, just waiting still

 

I ended up taking the coin back to the LCS where I bought it. They were very kind and exchanged it for a spot free one.

 

I have some spots on some 60's Cameo halves I would like to remove but have not tried. I would assume the TPG's would remove them if there was a way to do it. I have not heard of one. Yes I did the eraser deal and on bullion that is fine but not on one that has numismatic value.

I am going to try Oxalic acid ( I am not sure what concentrations I will use ) when I actually find a coin with milk spots. Maybe that is the good news

I brought home some oxalic acid from the lab and tried soaking an older wheat cent in it. It really removed all the brown toning, but left the coin with a kind of matte surface. I put a bright new cent in the solution for several hours and saw no deterioration. Will do more studies. Don't think it would hurt the silver, but also don't know if it would do any good.
