English-language sources routinely use the original Latin form "sestertius", plural "sestertii"; but older literature frequently uses "sesterce", plural "sesterces", "terce" being the English equivalent of "tertius". A modern shorthand for values in sestertii is IIS (Unicode 𐆘), in which the Roman numeral "II" is followed by "S" for "semis", and the whole struck through; but because this symbol and striking through letters are not always convenient, HS may be used instead, with the horizontal bar of the 'H' representing the strike through the numeral "II", rather than the letter "H".
