I picked these Clad layers up a while ago, but I noticed after I took photographs with a high definition macro lens that these two coins had PVC on the obverse on both of them. It really bothered me, so I inquired about the conservation service at NGC. I learned a couple things. Number one, in addition to paying the conservation fee, you also have to pay to have it regraded. Number two, it adds about an additional month to get your coins back. Number three, though I was not expecting it, removing the PVC did not improve the grade. I will have to see if the PVC comes back, but I doubt it (or maybe it was it slabbed with it on there?) Anyway, it was very well worth it. I cannot believe how great these look! And the PVC is gone! Top photo before, bottom photo after I have had glasses issued recently, and can see better. Those tiny specs of PVC won't get by me now for awhile. And I have since refused to buy coins even if I really love them if they have any on them (I just don't think knowingly buying them with PVC to then submit to have them cleaned is worth it. But in this case, it was). Nice job, NGC!
If something/anything about a coin initially bothers one, this isn't likely to change down the road and is why it's usually best to just avoid them. Of course there can be exceptions and is more of a general rule for those newer to their hobby. Glad all worked out and that you're pleased.
In my experience, they don't usually tell you what was wrong with it. And I agree, they look much better now.
wow it looks much better!! My last submission, NGC did recommend if I wanted a coin conserved and I think it was due to pvc so I said yes and they took care of it and then slabbed the coin. The coin did go up 1 grade. They had said it would be a 62 prior, after it was conserved it was a 63. The coin does look much better than when I had it in a 2x2 prior to sending it to NGC.
