PCGS Coin Imaging??

[Earle42]

That's interesting, I've never once seen a black toned coin in a slab. I think there's a point in the toning that is basically protects itself from further toning as long as the coin is stored properly.

I have three coins from ANACS which tarnished after they were slabbed. On one which is a MS-70 2006-W 20th anniversary, the other two are 2011 ASEs MS-69. I did contact PCGS and told them that they had started to tarnish. They said via Email that if want, they would restore them for nothing and re-encapsulate them if I enclosed the email they sent me with the order. The trouble I see is why just these three? They are stored in the same box as 21 other coins which are perfectly fine.

Wow...kudos to PCGS!

Why just those three?

My best guess is someone at the company accidentally contaminated the coin and the contamination was not visible to the naked eye.

Or maybe something was in the plastic slab itself when they put the coin in it. I was meticulous with my Kennedy Halves dipping each in acetone, allowing the acetone to totally evaporate, and then putting each in an Air Tite capsule. There had to have been something in one of those capsules (just one thankfully) b/c after storage for a couple of years, I found one half with a spot "growing"on it. I suspect pre-coin slabs can be "infected" as well(?).

I've bought a few coins in NGC holders that had dirt inside them like lint and one had a hair in it. I turned around and resold for a small loss on Ebay as sold "Damaged Holder"

I never returned them when bought as did not pay attention or see the stuff until a few months later by then most had settled on the coins themselves..one coin was stained by the black lint as it moved around settling on different parts on the coin.
