as above,is that common with panda coins? I thought at least these babies are safe...seems like all the mints are the same after all?...quantity over quality?...
Wouldn't say it was common (esp compared to maples) but it happens with some chinese coins, the gold ones are also prone to copper spots, which I have seen on a Perth Mint coin too. Edit to add: reasonably common enough for it to be a regular topic of conversation, they can be "cleaned" (neutralised I think) but not worth it for a 2011.
Quite common. A panda can be perfect for years then taken out of mint packaging & goes spotty in a week..
Alas, very true... I 'think' getting these Pandas conserved and slabbed may help in preventing some types of whitespots occurring... but some people say otherwise.
Many thanks Was wondering why I have no spots, I have both pandas and Canadian coins and no spots. I put it down to storing them with those moisture absorbent things in sealed plastic boxes(sistema) in the safe. And don't fiddle with them all the time.
I've seen several slabbed panda coins with grades MS69 and MS70 years 2007-2010 with milk spots, so slabbing is not panacea in itself. though I have no idea what "conserved" means
Chillidog, interesting. I wonder if what you are describing really is the answer to preventing this from happening? Do you put 1 gram packets inside to absorb moisture?
