Appeal for help with mine tokens

I WONDER if your readers can help me with my hobby, which is collecting brass embossed colliery lamp checks or tokens.

These are brass discs with the name of the colliery on them as well as the miner's number. The miner would draw this check along with his lamp from the lamp room before going down the mine.

I am trying very hard to obtain some lamp checks from the many collieries that once operated in the Cannock Chase Coalfield especially one from Brereton Colliery which was situated near to Rugeley.

I would very much like to hear from any one who once worked at and can remember local collieries working and any help they can give me in trying to obtain any lamp checks from them would be very much appreciated.
