Del Boy, Rodney, and Grandad are making some sort of cheap perfume just to earn money after Del has been losing most of his in a series of poker games with Boycie, which Del attributes to a "losing streak". Grandad shows Del a double-headed coin that he got off a Scottish man during the war, and advises Del to use it against Boycie. Grandad clearly remembers the story behind the coin as if it were only yesterday. According to him, the man said: "I want you to have something to remember me by, Trotter. Take me lucky coin." Then, he went (as in the Scottish man deserted, not died as Del thought).
