There were scientific research done in China. The findings is too technical for me. If I can find the link again, I will post it here.
I am almost afraid to look at the 2 5oz singapore show medals I have tucked away after seeing those pics that started this thread(or was it another thread?) ,I will now rest my case as far as milkspots and the varying opinions on Ncs preventing milkspots ...at the end of the day we still love the coins milkspots or not...............
If white spots develop after NGC grading, then you might be able to claim the insurance if/when you try to sell.
I not remember where i read it. But in the new coins ncs not make the process and send it to ngc withouth ncs. If you pay for ncs not allways in the new coins you will have the ncs process.
Yeah, I think that's somewhere on the NCS site. Says they evaluate the coins to determine if they need conservation. So, one could assume that if your coin looks nice, doesn't appear to have any surface residue they may just pass it right on to NGC. Which would suck, because then you just potentially wasted $10 or more depending on the coin/service. Just another way they take advantage of their customers/command of the market.
