Hello Stavros, I agree. When I look at the goals that base58 sought to achieve, (eliminating visually similar characters) I couldn't help but wonder why more characters were not eliminated. There is quite a bit of typeface androgyny when you consider case and face.

Yeah, I don't know why 1 was left in there, seems like a lost opportunity. Discarding l, I, 0, O, but then leaving 1? I wonder why.

I can only assume it was for a superstitious reason so that the original address prefixes could be a 1. This is the only sense I can make from it.
