For informative notes on actual usage of various symbols and abbreviations for currencies of the world, see e.g.
It depends on language-specific rules how currency symbols are attached to numbers. In English, the dollar and pound sign are usually written before the number (e.g. $1000), whereas in many other languages currency symbols are written after the number and separated from it with a space. And in Portuguese, for example, dollar sign is used as an escudo symbol so that it appears in place of decimal point (e.g. 30$00 is 30 escudos). Or rather was; escudo is not used any more.
Currencies can be denoted in several ways: words (in some language), currency symbol characters, or various abbreviations. The optimal choice depends on the context and intentions. When uniqueness, definiteness, and internationality (as neutrality with respect to national languages) are essential, the three-letter codes as defined in ISO 4217 should be used.
