Can the "$" symbol be safely considered as universal when making a graphic depicting money?

Want to get a sense of any best practices of using the "$" dollar sign in the context of an image in order to depict a universal idea of money.

Thanks for all the insights and weigh-ins everyone offered. VERY helpful!
