How many of you own a "shipwreck" coin? You think they came out of the ocean looking like they do in that nice shiny plastic? Ever seen those before and after pictures. When those things come out of the water they are hardly distinguishable as coins. They look like blobs of coral invested goo. They come out of the water and go into 5 gal buckets of ocean water and go straight to NCS. I have seen pictures of the receiving area stacked 4 or 5 high with these buckets of treasure. What they do is amazing. People abuse coins. That is a fact. Doing something to reverse some of that stupidity is good for the hobby.
For the record "dipped" generally means a process in which the coin is subjected to chemical bath that removes the top most molecules of metal. NONE of NCS processes "move metal" and they do not use Silver and Gold dips. One of their primary tools is Acetone. However they can buy a chemically purer form that is not available at Home Depot which in conjunction with a few other highly guarded techniques has done a lot for many an abused coin.
Conserving sea water effected coins is like comparing apples to oranges. Those coins needed to be saved (even if they have become a blight on the hobby at $500-$1000 per etched silver coin). But this no drapery coin needed no saving. It had stayed unchangd for 20 years and had no jet black corrosion forming encrustations on the coin.
Boy, I for one would be very surprised if none of the NCS processes remove metal. What do you think they use to get a Walker, Merc, or Morgan dollar to look blast white? MS70? Jewel-luster? Many have said that a quick dip and fast rinse in those 2 products will not be observable (ie no discernible metal loss to the eye). And that's probably true. But to suggest that no metal whatsoever is removed by NCS techniques sounds very far fetched indeed. In order to root out engrained PVC, corrosion, and othe environmental damage, one has to dig into the surface of the coin a bit further. That's metal loss.

Acetone won't remove toning yet some NCS conserved coins have had ugly toning removed. They must use some kind of dip contrary to what you are claiming.

Maybe they have one of those "magical felt pads" too.
