Even the most subtle of residue can make a large difference in the grade of a modern coin. Residues formed from years of improper storage, less-than optimum holders containing PVC or other volatile chemical, and even original mint packaging can all cause a coin to grade not quite at its full potential. A special tier price for conserving modern coins of these residues, as subtle as they can sometimes be, has been created to help those coins 1970 to date grade their best. The special $22.50 per coin rate includes both any beneficial conservation work and grading with NGC.

This Proof 1974 S Silver Eisenhower Dollar was recently submitted to NCS under the Modern Tier special. As an issue created to honor a World War II hero, this piece is a fitting modern coin to feature this week. An astute numismatist realized that conservation could help this coin grade to an optimum level. The conservators at NCS were able to remove the more obvious residues from the obverse of this coin as well as the more subtle residues on the reverse with skill as to not create hairlines in the mirrored fields. Following conservation, this coin was able to grade at a higher level than it would have without removal of the residues.
