In May 2018, Gordon Cook showed me something of interest that he had acquired. It was a metal Co-op token, perhaps preceding the more commonly known Bakelite ones.
Although in poor condition, the name “Blantyre Co-op Society Bread 3” could be made out. Perhaps these metal ones, prone to rusting were phased out when a more durable material came along? With no date on it, its difficult to assess how old it is, but may date back to the late 19th Century.
