Yeah they had pretty much no milk spots but they grew and suddenly they were half covered. I've been storing them in a mint tube @Bman33
Dang, I bought some Superman Maples that I love. I was hoping to hold on to those forever. Is there potential for Milk Spots on those too?
Yeah there probably is because I bought those maples from diff sellers and they both developed spots, so it would have had to been the mint. Hopefully it doesn't happen to yours @Bman33
If the tubes were Canadian made, they may be different than the US Treasury Green top tubes for ASE. Those tone faster than any 'doctoring' setup I know. Perhaps toning is perhaps not the same as milkspots, but I would not use them as it is most likely some chemical reaction.
I've had some dealers offer $1 to $2 less for milk's, my response "its silver", i'm told it's a boron reaction in the final clean, ? none of my coin prior to 2010 has never had this response.
