Coffer Sports did not manufacture badges. They commissioned them from firms in Birmingham's jewellery quarter and distributed them to traders across the counntry. I dealt with Coffers from 1972 to the early 1980s. The last contact I had with them was a conversation with Malcolm Coffer on Wembley Way before the FA Cup Final of 1985, but by that time the firm had gone into liquidation. Some of the dies were sold and used by other people to make badges, usually in soft enamel.
