1c lilac telegraph stamp with inverted value is actually a forgery, but it is quite expensive nowadays. The stamp appeared for the first time in the 4th Ferrary auction in June 1922 in Paris, and appeared again in 1993 in a Dutch auction. In October 2010 the stamp was sold for $3,168 at Corinphila auction. This is one of the most appealing philatelic forgeries of the Netherlands.
