Discover the many factors that contribute to the 7000+ varieties that make-up the Machin series; value, color, phosphor/fluor, paper, perforations and printing processes. Deepen your understanding of origins and artistic design. Explore the technical aspects of these stamps that allow their interaction with automated facing and sorting equipment, including the technical complexity of the Non-Value-Indicating (NVI) printings.

For the past decade, Steve McGill has focused on collecting the stamps of the U.K., with special interest in exhibiting the Machin series from its forerunners to the latest Non-Value-Indicated printings. He has researched the full range of factors that make the series rich in varieties. These factors include the artwork, paper-gum, phosphor-fluor, perforation and printing processes. This study has helped McGill to produce three Machin-related exhibits that have been shown and vetted in the U.S. and international stamp shows. His research has included an IAP grant to study stamp phosphorescence at the Smithsonian Philatelic Museum.

Steve’s Machin exhibits have won large-gold awards; the first Brett Cup award and a number of APS research medals. His Denominated Machin exhibit content was published in 2019 by the Forschungsgemeinschaft Grosbritannien e.V in Germany as part of the Conserved Heritage Volume VIII. McGill has also lectured extensively on the Machin subject in the U.S., U.K. and Germany.

Additionally, Mr. McGill collects central Europe, China and parts of Scandinavia. He belongs to several organizations related to the hobby including; the Royal Philatelic Society of Canada, Great Britain Philatelic Society, the Great Britain Collectors Club (Past President), The China Society, The Rocky Mountain Philatelic Library (Board Member), The Rocky Mountain Stamp Show (Past Chairman) and is a Fellow of the Royal Philatelic Society of London.
