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.

Professional conservation should not be confused with "Coin Doctoring", in which an attempt is made to improve the appearance and grade of a coin through deceptive means such as artificial toning and where unaccepted or unorthodox methods are employed.

The PNG Board of Directors has adopted this initial definition:
Coin doctoring is the action of a person or the enabling of another to alter a coin's surface or appearance, usually to diminish or conceal defects, and thereby represent the condition or value of a coin as being superior to its actual condition or value.

Among the practices defined as doctoring are effacing hairlines by polishing or manipulating the surfaces of proof coins, applying substances to the surface of coins to hide marks and defects, hiding marks or otherwise changing the appearance of a coin by adding toning, adding chemicals or otherwise manipulating the surfaces to create �cameo� frost on the devices of proof coins, and making a coin appear more fully struck by re-engraving portions of the devices, such as re-engraving bands on the reverse of a Mercury Dime or adding head detail to a Standing Liberty Quarter.

Altering dates or mintmarks or other struck portions of a coin to make it appear to be from a mint date or type other than that of origin, and altering business strike coins to make them resemble proof issues are also examples of coin doctoring. This definition is not intended to be all-inclusive, but only illustrative of forms of coin doctoring.
