I'll stick with the "quadruple plate" reading but the name of the specific company remains a mystery. The phrase 'quadruple plate' refers, of course, the the thickness of the plating. The more plating, the longer the item should last; but the value is not greatly affected since the layers of silver are so thin.
Based on the relative size of the quarter and the item, I'll stick with DCM 's original call of a creamer.
