They are relatively vague on the website. Describing what they do as : "Numismatic conservation involves examination, scientific analysis and reliance upon an extensive base of numismatic knowledge to determine the nature of a coin’s state of preservation and the extent of any damage. Conservation also encompasses appropriate procedures to protect the coin’s original appearance and to guard against future deterioration to whatever extent possible." and more "The expertise of NCS technicians has long been needed in numismatics. Not to be confused with undesirable cleaning, proper numismatic conservation involves examination, scientific analysis and a reliance upon an extensive base of numismatic knowledge to determine the nature of a coin’s state of preservation and the extent of any damage. NCS is uniquely qualified to meet the conservation needs of the hobby." There're 1000's of posts on CoinTalk about caring for a coin's appearance. So despite all the tried and true knowledge the experts on CoinTalk have compiled what "secrets" or "proprietary knowledge" or "hocus pocus" does NCS do? And how come they make it seem they are the ONLY place on the planet that can and should do this service for you? Please educate me dear sirs.
NCS is not saying they are the only organization (or individual) who can successfully perform such services. What it boils down to is that if you don't know what you are doing, you may be just as likely to ruin a coin. That is why they provide such services. Chris
If they did not keep what they do and how they do it a secret, then there wouldn't be much need for them would there ? The company is a business, the purpose of a business is to make money. And you don't make money by giving away the secrets of your business. As I have said many times, learning what chemicals and the specific proportions to use is the easier part. The hard parts are gaining the experience to use them correctly, and being able to judge which coins can be helped and by what, and which ones cannot. It's like any other profession, you pay professionals to do the job for you because you don't know how.
