Sixpence (Irish coin)
The sixpence (6d; Irish: réal or reul Irish pronunciation: [ɾˠeːlˠ] RALE) coin was a subdivision of the pre-decimal Irish pound, worth 1⁄40 of a pound or 1⁄2 of a shilling. The Irish name réal is derived from the Spanish real; for most of the 19th century, a pound sterling was equal to five U.S. dollars, and a dollar was equal to eight reales, so that a real was equal to 1⁄40 of a pound.
