    Cash? 10 more to go... – Anthony Pegram Sep 14 '11 at 20:41

    Oh good lord, is it that obvious? – Cat Sep 14 '11 at 20:45

    Typical face-palm question. Don't feel bad, I was complaining to a coworker the other day that I wished there was some way I could copy and paste from my computer to paper... the response was one word "Printer"... sigh – CaffGeek Sep 14 '11 at 21:08

    I'm ambivalent about closing this: it's pretty basic, but not exactly obvious if you're not familiar with the word "cash". Quickly Googling didn't turn up any results that made this connection obvious, at least. Made the answer community wiki so if someone in the future has the same question, at least there's an answer floating around on the internet. – user8 Sep 14 '11 at 22:12

    It's not even necessarily obvious if you know the word. When I see "$" I think "dollar" (or lately, "jQuery"), but not cash. – David Z Sep 14 '11 at 23:39

I suppose that's not obvious for non-native speakers, but as mentioned in the comments, the dollar sign is representative of money, synonymous with the word "cash", which is a homophone for "cache".
