$ appears to have evolved ca 1775 in the United States from a common abbreviation for pesos, also known as piastres or pieces of eight, a P/raised-S ligature PS that passed through a stage resembling ֆ.[1] It was used in the US before the adoption of the dollar in 1785.[2]

Usage notes edit

When used as a currency symbol, $ precedes the number it qualifies in English, despite being pronounced second. For example, “$1” is read as “one dollar”, not “dollar one” unlike the usage in languages such as French or German: “1 $”, “2,50 $”.

When used for the Portuguese escudo, $ is placed between the escudos & centavos, 2$50. The official symbol for the escudo is   (with two bars), but that form is unified with the single-bar form in Unicode. A single-bar dollar sign is frequently employed in its place even for official purposes.

    • A$, AU$ (Australian dollar); C$ (córdoba); NT$ (New Taiwan dollar); NZ$ (New Zealand dollar); R$ (real)
    • English: C$ (Canadian dollar; Confederate dollar); U$, US$ (United States dollar)
  • (variable): English: $DEITY (generic deity)
