While The Chance of a Coin shows up first on the list of Peregrine and Blade stories, it wasn’t the first written, and was more done somewhere in the middle of the current stories.

Why it shows up first is that it is more of a vignette, a very short piece of flash fiction that gives a brief introduction to the two main characters, Peregrine and Blade, and a brief insight into what they are like, and what drives them. And it still manages to tell a story.
