Original mint packaging is quite often not the best for storage of modern coins. Even gold coins issued within the last few decades can be just as susceptible to the development of a haze as silver or nickel issues. This haze can be unattractive and will cause the coin to grade lower with NGC than it would if the haze were not present.

The conservators at NCS have developed techniques to remove the haze from the surfaces of modern gold coins just as with silver or nickel issues. This 1985 500 Peso from Mexico was struck in proof quality and issued in honor of the World Cup Soccer event held in Mexico that year. It had developed a slight haze that can be seen particularly around the date. The conservators at NCS were able to remove the haze allowing the coin to grade fully to its potential with NGC. Being a modern coin valued less than $3,000, this coin was able to be both conserved and graded for the lower fee of $22.50 by using the NCS modern rate.
