Pre-Decimal Issues
The first Machins were issued in 1967 and were in use until the UK changed to a decimal currency in 1971. These Machins came in two sizes, with the four higher value stamps being the largest.
Small Size (21mm x 24mm)
Large Size
Decimal Issues
The decimal Machins have been issued throughout Britain's period of decimalisation, and continue to be produced today. During the 1970s and 1980s, the Royal Mail issued 12 Machins in a larger format. Other major variations include:
Elliptical Perforation: In 1993 the Royal Mail started issuing Machins with two large elliptical perforations, one on either side, as a security feature. Some Machins have both standard and elliptical perfs, but those issued after 1993 only have the ellipticals. EME Images: In 1997 a new profile of the Queen was used on Machins. EME (or Electro-Mechanically Engraved) images are created by computer and therefore offer better detail in the image. Regional Issues: These Machins were issued with a heraldic symbol in the top left hand corner. These represent the Isle of Man with the Three Legs of Man symbol; Northern Ireland with the Red Hand of Ulster symbol; Scotland with the Lion of Scotland symbol and Wales with the Welsh Dragon symbol.Small Size (21mm x 24mm)
Large Size (30mm x 35mm)
NVI (Non-Value Indicator) Issues
NVI (or Non-Value Indicator) Machins first appeared in 1989 in an attempt to negate the need to keep issuing new stamps after each postal rate change. They are marked 1st and 2nd for the two classes of post in the United Kingdom. The E NVI stamp represented the standard letter rate to Europe.
