Why would a javascript variable start with a dollar sign?

I see people using the dollar sign in front of variables when using jQuery. Is there any reason behind this? I'm I missing something basic or is it just a common practice?

It's a common reference to a jQuery wrapped object. It makes reading the code easier to know which variables are jQuery wrapped.

//Item has been cached for later use in the script as a jQuery object.

var $item = $(this);
