An interesting green enamel lapel badge for the Clay Cross Company based near Chesterfield. The business was founded by railway pioneer George Stephenson in 1837 and ran coal mines, ironworks, brickworks and pipe factories at Clay Cross, Derbyshire. Further details of the firm can be found on Wikipedia.
The badge is made by the Birmingham Medal Company and the meaning of the additional letter 'J' is not currently known (at the time of writing no other badges with any other letters are known to exist). If you know more about the use of that letter, drop me a line.
