s

Lower case S with strikethrough. The markup to display it is as follows:

<del>s</del>

It can also be written:

~~s~~

s

Example:
s250.32

I think it is a nice twist on the dollar symbol and can be rendered in any font.

Note that the capital doesn't look as good:

S s

and a delta with overstrike for steem backed dollars:

∆
