X Values Machins

X Number stamps were issued from 1971 to 1996. X Value Machins feature a solid colour background, the Machin head, and a decimal face value.

X Number Machins were printed by either Harrison (X841-X995), Waddington (X996-X999), Questa (X1000-X1024) or Walsall (X1050-1058).

A number of the X Value Machins feature one or two imperforate edges, where there is a straight cut edge rather than perforations.
