In the 1980s, three specimens of water-warn macphersonite were found "somewhere between 20 and 30 level" (Gebhard, 1999). They were initially mistaken for leadhillite. In 1995, a single well-crystallised specimen of "leadhillite" with kegelite was purchased by German collector Georg Gebhard; it turned out to be macphersonite. After the mine had closed, in 1996, a single specimen was sold as anglesite to American dealer Charlie Key, who believed it to be leadhillite. It later proved to be macphersonite (Gebhard, op.cit.).
