Prussia. Wilhelm II gold Proof 20 Mark 1907-A PR66 Cameo NGC, Berlin mint, KM521, Jaeger-252. The single finest graded example of this date at NGC, and it's easily to see why, with skillfully frosted devices, visually distraction-free fields, and a strike that confidently defines the central detail as well as the far outer dentilation on both sides. Close magnified inspection only serves to further confirm the rarely matched quality, as the surfaces are not only high-end for the grade, but sit on the absolute cusp of Superb Gem (67) quality. Certain to attract addition attention thus.
