In 1926 the government of the newly founded Irish Free State formed a coinage committee to plan for a new Irish coinage.

In 1928, the sixpence Irish coins depict the Wolfhound's head looking back. The Irish Wolfhound is a historic sighthound dog breed from Ireland that has inspired literature, poetry and mythology. The Irish Wolfhound is a historic sighthound dog breed from Ireland that has, by its presence and substantial size, inspired literature, poetry and mythology.
