What were these mystery checks/fobs used for?
I am not sure if these brass embossed discs (32 mm diameter) are really checks or key fobs. None of the many I have seen to date have numbers or initials stamped on them. Most collectors attribute their issue to the UK's coal mining industry. The date of their issue is not certain but they are thought to have been possibly made and issued in the 1980s.
Can anyone throw any light on what these checks are or were used for? I would be greatful for any information concerning them.
I remember that at various times in the 1980s Kellingley Colliery achieved and broke several production records. I'm fairly sure that as well as the more familiar pseudonym of "The Big K", Kellingley was also know locally during this time as "King Coal". So could these checks be mementoes of that period? Possibly made to celebrate the occasion when the pit achieved one or other production record. Similar checks/fobs were issue by the N.C.B. to miners at Grimethorpe Colliery in 1981 on the occasion of one of their record production runs. The management at Kellingley certainly commissioned various commemorative items through out the 1980s when the men broke production records. These included presentation medals, Hip Flasks and Tankards.
