How many lines?

Some are saying it was always written with one vertical line, some with two and some with both.

The origin of the vertical line is an interesting story itself. Originally, the US used Spanish Peso, which was written P with a supercripted "S". Writing PS so many times caused them to merge into the S with a line though.

Sometimes, however, it appears with 2 vertical lines, but there's no doubt the single line one seems dominant - just take a look at your keyboard, for example ;-)

There is a variation of the origin story which is simpler. It just says it originated by writing U directly over S, cutting out the bottom of the U. This would result in two vertical lines. Even more curious is the UK pound symbol is sometimes seen with two horizontal lines, and sometimes with one...
