A Northern Rhodesia 1963 Arms ½d error block of 12 is valued at £35,000-45,000 ($55,731-71,654) ahead of a sale at Spink London on November 25-26.
The eagle on the shield is usually coloured orange, but is white in this printing.
The issue was created following the dissolution of the Federation of Rhodesia and Nyasaland in December 1963, but was withdrawn a few months later after Zambia declared independence in 1964.
It's described by the auction house as "a unique and exceptional multiple of exhibition standard."
We have this rare strip of Rhodesian 1966 one-shilling error stamps available.

KUT stamps bear the name of each of the three colonies they were issued in. They continued to circulate until 1977, when they were replaced by local designs.
