A guinea was a form of British currency. Despite being a nominal prisoner, Polly stole twenty guineas from British Army Lieutenant Algernon Ffinch in 1746. (TV: The Highlanders) Edward Hardiman once made a wager for one hundred guineas that he was not able to cover, much to Jack Harkness' displeasure. (PROSE: Best Friends) In 1893, Jenny Flint offered a woman named Abigail (The Crimson Horror)| a guinea to create a diversion in the new recruits' receiving line at Sweetville.

Behind the scenes
The exact nature of a guinea is never really discussed in the DWU. In fact, it was worth a variety of values, mostly owing to the fact that it was traditionally made of gold. It's most common value was slightly more than a pound sterling.
