Rial Público Deposited
A silver coin of Morocco which occurs in both round and rectan- gular form. It corresponded to the Span- ish Real and was divided into thirteen and a half Ukkias. For a detailed account of its comparative weight and fineness see Noback (p. 243).
The Rial of the modern Morocco coinage is sometimes known as the Piastre, and is subdivided into one hundred Centimos. It corresponds in value to the quarter Franc or quarter Peseta, and must consequently not be confused with the Turkish Piastre. See Abbasi.
For Zanzibar, the Rial has been issued since A.H. 1299 with Arabic inscriptions, and is the size of a dollar.
