1867–83 £1 Brown-Lilac Watermark Anchor on White Paper — The Rarest Mint Standard Postage Stamp of GB

A tremendously rare and highly desirable high-value, this fresh mint example is well centred and displays excellent, rich colour. The stamp retains part original gum and a vertical gum crease is noted purely for accuracy, without detracting from its most attractive overall appearance, prized for both its scarcity and visual appeal.

An outstanding example of one of the rarest classic British stamps with only 20 recorded by Karl Louis in private hands on either white or blued paper.

Stanley Gibbons Catalogue value: £140'000.

Expertise: Accompanied by a British Philatelic Association Certificate (2025).

Provenance: From the illustrious Dale–Liechtenstein collection.
