Can services like NCS remove fingerprints or corrosion?

I've seen many coins with fingerprints, or dark/black spots of what appears to be some corrosion, on otherwise nice coins which (one can only presume) would benefit by the removal of these impediments.

I've not read much in this forum which speaks to this specifically, nor read of any personal experience regarding the success of companies like NCS, for instance. They show an example of a gold coin severly damaged as a result of fire, and it turned out looking as if it just left the Mint... how they do that?

IN any case, I have a few coins with prints I was considering sending in to NCS, but before I do, anyone care to post their own experience (be it NCS or anyone/thing else)?

I do not have any experience with NCS, although I have heard (here and elsewhere) that they do good work. Fingerprints, when left on a coin (particularly proof, mirror surfaces) will etch the metallic surface due to the natural acids in skin oil. Once etched, it would take sophisticated work to remove the problem (perhaps a laser could do it, but I do not know). Serious corrosion, again, attacks the surface and removes metal. Perhaps a phone call to them would best serve you. Cheers, RickO

I see no way that putting back what is gone as being acceptable to the majority of collectors.

No to both questions.

You have to be careful about saying anything about NCS since they are asscoiated with NGC. Thats why there are not many posts about them. So much for the free exchange of ideas.
