Are NCS coins less valuable?

Are NCS coins less valuable? Technically doesn't NCS clean coins and doesn't cleaning lower the value of a coin?

[CHRISS]

What lowers a coin's value is "improper cleaning." Improper cleaning in the numismatic community is cleaning that leaves a coin's surfaces hairlined, or with impaired luster, scratches, unnatural color, etc. which make the coin less desirable and thus less valuable. The conservation that is performed at NCS does not alter the original surfaces. Our methods remove foreign materials and residues from the surfaces of coins in an attempt to bring out the piece's original beauty. We rely on intensive visual examination and numismatic knowledge to determine the level of a coin's preservation and degree to which foreign materials might be safely removed without the problems associated with improper cleaning before any work is performed. There are no methods of conservation that NCS applies that would the problems associated with improper cleaning.
