First off, ANY CAC approved Mint State 18-S nickel is incredibly RARE! This impressive, lustrous beauty has a gorgeous steely nickel color that has a dusting of soft iridescent patina. Hints of gold burst forth when rotated in a light. High end for the grade, deserving of its Gold PQ sticker. PCGS 199, NGC 197, CAC 9. There has not been a PCGS/CAC example sold in auction since November 2014, where one sold for $4,994, prior to that, one sold for $4,259 in February 2014. The current PCGS Price Guide value is $3,500 and this one should sell for more, as it is RARE to find with CAC approval. Cert. Number 30434799 PCGS # 3940
