This sign is a very interesting one. I do not know where it originated in. And why do we use it? How does $ sign relate to dollar?

Does it mean money? Sometimes I've seen it with double lines striking through it.

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information.If this question can be reworded to fit the rules in the help center, please edit the question.

It is an interesting question but wikipedia has it covered en.wikipedia.org/wiki/Dollar_sign – user24964 May 2 '13 at 14:39
The Wikipedia response is very tentative. If the question can be "definitely and permanently answered by a single link," I don't know what it is. – gmcgath May 2 '13 at 18:34

Per Wikipedia, the leading hypothesis is that the "U" & the "S" were written overtop of each other, and eventually the two bars of the "U" were collapsed into one.
