CZECHOSLOVAKIA. 100 Korun, 1955. Prague Mint. NGC MS-67.

KM-45. Struck to celebrate the 10th anniversary of the liberation of Czechoslovakia from Germany, the current example is the single finest certified at NGC for the type. Swirling cartwheel luster lights up subtle multi-hued toning on both sides, with more colorful toning at the edges framing the devices. Frosty and incredibly eye appealing, this example will stand out in a collection of 20th century crowns.
