Lampchecks and tokens
Lamp checks (or 'tokens' or 'tallies') are one of the most popular coal mining objects collected by both museums and the general public. They basically informed colliery management of who was in work but became vital when rescue services needed to know how many men were actually underground during an incident such as a fire or explosion. Colliery check systems apparently became common during the late nineteenth century and became mandatory in 1913 after an amendment to the 1911 Coal Mines Act.
