Examples of coins condition before conservation
Malaysian collectors are confused with the term "Conservation" and "Doctoring". "Coin Doctoring", is an attempt to make the grade of a coin through deceptive means such as artificial methods are employed to make the coins more beautiful such as mechanical repairs are made like filling holes, smoothing out scratches, and re-engraving of detail. This is what you should be afraid off !
Malaysian collectors are unlike westerners collectors, whereby westerner collectors like their coins to be conserved especially the silver coins. After conservation the coins won't develop mikly spots or oxidise for many years to come.
After conservation service by NCS
Malaysia is in the tropical climate where we have excessive moist and heat and that will erode our coins more rapid. Light surface corrosion, or toning are the common signs of most coins in this state.
Toning causes copper coins to turn brown, and silver and nickel coins to develop hues of blue, red, green, purple, and other colors. If left untreated the coins will deteriorate further to advanced stages of corrosion can damage a coin’s surfaces. If the toning process goes too far, the coins turn black and the actual surface of the coin may be ruined forever.
These are few examples of coins being conserved by NCS
Eight metals are primarily used in minting coins, tokens and medals: platinum, gold, silver, copper, aluminum, zinc, tin, and nickel. Silver, copper, aluminum, zinc, tin and nickel are most sensitive to the environment. If you stores these coins in your house without air-conditioning they will oxidise rapidly over the period of 2 years (similarly to our Nordic gold coins).
NCS will evaluate the material made of your coins and use the best method to conserve them without damaging the coin surface and return your coin back to its original appearance.
Please contact me if you want to send your coins to NGC for grading or NCS for conservation service where i have regular shipments over to them every month.
Thank You.
Happy Reading,
