Penney (also spelled Penny) is a common surname of British origin. The name Penney dates from the ancient Anglo-Saxon culture of Britain. It was derived from the Old English "Penig," denoting a coin (cognate with German "Pfennig"). The penny was the only unit of coinage in England until the early 14th century; as such, it was a coin of considerable value. https://en.wikipedia.org/wiki/Penney
