The effects of improper storage and exposure to environmental contaminants can frequently diminish a modern coin’s appeal. These harmful conditions can lead to the hazing of surfaces, spots, and other surface detriments that can adversely affect a coin’s grade. Quite often the original mint packaging can exacerbate much of this problem and this holds especially true for Chinese Panda coins. Original mint packaging can be made of the questionable materials and rarely airtight to the environment. Professional conservation can help alleviate many of these problems to help the coin both grade better as well as be more attractive and stable for long-term appreciation.

To help modern coins to grade at their best, NCS has a special Modern service. For one fee of $22.50, modern coins will be conserved having their haze, residue, and spots as much as possible removed as well as graded.

This 1983 Chinese Panda 10 Yuan silver coin was recently submitted to NCS using the modern coin tier. A thick haze was hiding the true surface of the coin. Such thick hazes are commonly encountered particularly with Chinese Pandas and can lead to a permanent and unattractive alteration to the mirrored surface otherwise known as “burning.” This Panda was able to have the offending haze removed to reveal a bright flashy mark free coin that did grade with NGC.
