Well, I'm a bit bummed. Looking through and organizing some stuff and came across 6 2012's I picked up a few years ago. Of the 6 1 is pristine while the other 5 (please see pic) have the same issue. These were stored in original capsules and in the same box as some 2010's and 2011's. The 2010s and 2011s have no issues. You are looking at the coins with the capsule off. Hmm.
Aww that sucks. It's happened to me too many times. Haven't checked the few pandas I have in years but last time I've seen them they were ok but so many other big name coins all milky and spotted crap. I guess I'm going to stick with bars from now on
I've drastically cut down on my silver bullion purchased (Perth mint and Pandas) for the reason of white spots. I've finally converted to gold...even 1/10, etc...
2004, 2008, 2011, 2012, 2013 always had this issue even if is graded. U can easily can this stupid haze especially you put in humid places like cupboard near washroom, wardorode and so on. I have few Ngc facing this issue.
I think to do with Temperature... Best to put them in a steady environment... say a cooler place.... wrapped up in special plastic bags that is not Biodegradable
