              Shop prices in mainland China and Taiwan are usually marked with 元 after the digits. In mainland China, using '¥' as well as RMB to denote the currency is common.
And here's the link on how to get the ¥ character in unicode or with HTML entities.

              On the mainland I've never seen the ¥ symbol outside financial institutions.  It's always RMB or more likely 元.  Admittedly most what I have seen is Shanghai and nearby locations.

                @Loren: Okay, who's going to put the [citation needed] tag on the Wikipedia page then? :)

            I think you possibly want CNY (ie. Chinese yuan). Also sometimes known as RMB.
