KMPS118 A superb set. Nine beautifully engraved, heavily frosted, gem proofs. Cased and in perfect condition.  A scarce set. Four of the eight coins were struck in silver. The rise of silver in 1980 caused many of these sets to go into the melting pot. I was helping a local coin dealer at the time and personally saw about 25 of these sets consigned to the smelter just from his small shop. 2.8721 oz of pure silver content  FDC
