KM-304. Tied for second finest graded at NGC or PCGS. First issue. A common type but quite rare in this grade. Fresh with a trifle of weakness on the eagles breast. Frosty white surfaces dripping with original mint luster, brilliant and exceptionally attractive. NGC MS-63. From the Alex Siegel Collection.<p>NOTE: An MS64 hammered at $6,500 in our January 2017 NYINC auction.
