Machin Definitives Overview

The Machin Definitives series, featuring Queen Elizabeth II's iconic portrait by Arnold Machin, is one of the most recognisable and enduring designs in philately. First introduced in 1967, these stamps have become a cornerstone of British postage, evolving over time to reflect changes in technology, postal requirements, and currency.

History of Machin Definitives

The history of Machin Definitives dates back to the late 1960s when Arnold Machin created the plaster relief of Queen Elizabeth II that would grace these stamps. The design’s simplicity and elegance have ensured its longevity, with many variations issued over the decades.

Key moments in the series' history include the transition from pre-decimal to decimal currency in 1971 and the introduction of security features in more recent years, such as phosphor bands and security slits, designed to combat postal fraud.

Decimal and Pre-decimal Machin Definitives

The transition from pre-decimal Machin stamps to decimal Machin Definitives in 1971 marked a significant change in British postage. The earlier pre-decimal issues carry values such as 1d or 2/6, while decimal issues align with the modern currency system. Collectors often seek to complete sets of both, noting the differences in watermarks, colour shades, and print techniques.

Differences Between Machin and Wilding Definitives

Before the Machin series, British stamps featured the Wilding Definitives, which were issued from 1952 to 1967. The Machin Definitives replaced the Wilding portrait stamps, offering a more modern, minimalist design. While the Wilding Definitives are known for their decorative frames and photographic detail, Machin Definitives are celebrated for their sculptural simplicity.
