* "The chief Anglo-Saxon coin, and for a long period the only one, corresponded to the denarius of the Continent . . . [and was] called penny, denarius, or denier." R. S. Poole. The ancient silver penny was worth about three pence sterling (see Pennyweight). The old Scotch penny was only one twelfth the value of the English coin. In the United States the word penny is popularly used for cent.

What penny hath Rome borne,
What men provided, what munition sent? Shak.
