I've been listening to the BBC Radio show Hancock's Half Hour which was set in working class 50s/60s Britain before we decimalised our currency, and being in a very lower-class cockney London setting it's full of slang terms for currency such as bob, knicker and tanner, but one term I'm having trouble translating is "half a dollar", as in "The Chef That Died Of Shame" (around 4:49) in which Tony is running a horse-drawn hot pie stall.
What would "half a dollar" mean in real money at the time? Where did the term come from?
Tony Hancock (the character shared the name with the actor) was always depicted as an old and old-fashioned character too, so it may be a lot earlier than the broadcast dates, any time from the 1900s to 1945 based on the standard age of the references in the show.
