Old Saxon alphabet: despite being on an alphabet page, it’s very clearly separated from the letters.

I’m not at all convinced that it was ever what you might call a letter of the alphabet. Although it seems to not have been rare to group it with the letters in some way, I have received the impression it wasn’t particularly common, and that it wasn’t how people generally thought of it. Nowadays we would draw a clear distinction between letters, numbers and symbols (maybe we have more symbols? though certainly fewer ligatures/abbreviations like Ƿᵉ), and call the alphabet just the letters, but I get the vibe that maybe “alphabet” wasn’t so strictly just the letters. But I handwave liberally and provide no sources in this mostly-uneducated suspicion of mine.
