The pound was the currency of Delaware until 1793. Initially, the British pound and foreign coins circulated. This was supplemented from 1723 by local paper money. Although this was denominated in pounds, shillings and pence, the notes were worth less than sterling, with 1 Delaware shilling = 9 pence sterling.
The State of Delaware issued Continental currency denominated in £sd and Spanish dollars, with the dollar equal to 7 shillings and 6 pence. The Continental currency was replaced by the U.S. dollar at the rate of 1000 continental dollars = 1 U.S. dollar.
