Quadrupla Öffentlichkeit Deposited
A large Italian gold coin which obtains its name from being four times the size of some other current gold denomination.
It occurs in the Papal series of four times the value and weight of the Scudo di Oro; the Emperor Charles V struck it for Naples and Sicily in 1547; Alberico Cibo for Massa di Lunigiana; Ferdinand Gon- zaga (1612-1626) for Mantua, etc.
It is common to Savoy where its original value was four Scudi di Oro and later eighty Lira. In the Milan coinage it is found during the seventeenth century, and is known as the Doppia da Due.
