PNG Adopts Coin “Doctoring” Definition
The Professional Numismatists Guild (PNG) has created a definition of coin “doctoring” and now officially included it as one of the prohibitions in the organization’s By-Laws.
“The deliberate and unacceptable alteration of a coin in an effort to deceive is a complex matter. Everyone seems to know what coin ‘doctoring’ means, but it’s a difficult thing to concisely and substantively define,” said Paul Montgomery, PNG President.
“After extensive discussions and consultation with both Numismatic Guaranty Corporation (NGC), the official grading service of PNG, and with executives of the Professional Coin Grading Service (PCGS), the PNG has created its first formal definition of coin doctoring,” Montgomery added.
PNG already required disclosure of information about altered coins.
“Section seven of the PNG Code of Ethics specifically states that PNG member-dealers must refrain from knowingly dealing in counterfeit, altered or repaired numismatic items without fully disclosing their status to their customers. Section four of the Code prohibits misrepresenting the quality of a coin,” said PNG Executive Director Robert Brueggeman.
“Adding a more specific definition of coin doctoring is a major step toward helping the PNG review any complaints against members accused of compromising ethical standards established by the organization. We now have an enforceable criterion for our membership.”
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.
“As of today, no one has filed any formal complaints with PNG or presented evidence directly to the PNG of alleged coin doctoring by any of its members. However, we have been closely monitoring developments, and are taking action regarding a civil court lawsuit over alleged coin doctoring that was filed by PCGS in May of this year,” said Brueggeman.
Founded in 1955, the Professional Numismatists Guild is a nonprofit organization composed of many of the top rare coin and paper money dealers in the United States and other countries. PNG member-dealers must adhere to a strict Code of Ethics in the buying and selling of numismatic items.

The goal of the NGC Collectors Society is to enable collectors to build better collections by providing the tools, community and resources that they need. Through feedback received from members, new features are planned and developed. The addition of the Collection Manager is the most significant enhancement to the Collectors Society toolkit since the initial launch of the NGC Registry in 2002. Since that time, over 500,000 coins have been registered in nearly 60,000 individual NGC Registry Sets.
During the period from July 18, 1794 to November 12, 1796, a total of 39 deposits of silver were brought to the Mint. Among those were five deposits in August 1794 that were the exact fineness of standard silver (89.24% pure). Only seven of the remaining 34 deposits were lower-purity than standard silver, but those seven deposits totaled 98,556 gross ounces of silver, or nearly 25% of all the silver deposited during that 29-month period. The result was a necessity for the Mint to supply more than 2,100 pounds of copper to bring the silver deposits up to standard. At the prevailing rates, the cost of that copper alone was approximately $560. Copper collectors will be quick to point out that the cost of the alloy was equal to a little over 70,000 additional large cents that could have been minted.
