A unique block of four Rhodesia two pence Admiral issues is valued at £25,000-35,000 ($1,945-58,723) ahead of Spink's June 17 auction in London.
The lot is in unmounted mint condition and details the sheet number (354) to the bottom right.
The Admirals (so called because they depict King George in his admiralty uniform) were issued during the early to mid 20th century in the commonwealth states of Canada, New Zealand and Rhodesia.
The Rhodesian examples were released between 1913 and 1924 and are separated into distinct series, those issued before 1922 and those that were produced after.
While the image on both remains identical, the paper and gum used on the later examples is clearly different.
Additionally, the post-1922 issue was never sold within the state with the result that only the earlier examples are found used or on covers.
A strip of three green five pence issues, one of two recorded examples, is another highlight.
The stamps are imperforate at the margins and retain a significant quantity of the original gum. They carry an estimate of £20,000-25,000 ($33,556-41,945).
A unique one shilling block of four with the original gum are expected to achieve an identical sum.
We have this rare unmounted strip of six Rhodesian error stamps available.
