Good on you Charles... well spotted.

The 1935 Silver Jubilee set is a common enough stamp, and can be purchased for a couple of pounds. However there is a variant, and Hansons were astonished to discover an example of this at their recent stamp valuation day.




In 1934 a stamp design was sought to commemorate the 1935 Silver Jubilee of King George V. The King, a very keen stamp collector, was consulted on the design process and was given the final decision on the colours. He opted for the Ultramarine shade, however the printers managed to print several hundred sheets in the wrong shade. Most of these error sheets were destroyed but four managed to get into circulation; whilst three went to a Post Office in Edmonton, the destination of the fourth remains unknown.


A sharp eyed local gentleman noticed the variation and bought the remaining stocks, sending some to friends as keepsakes. Of the possible 480 stamps that escaped destruction, it is estimated that maybe only 200 or so exist today. The error stamp known as the Prussian Blue Jubilee is arguably the most famous colour error in GB philately and as such is very popular with collectors and investors alike.


Hansons Auctioneers are delighted to announce that the September stamp and coin sale will include a fine mint example of the Prussian Blue discovered by Hansons stamp expert Phil Ives, together with an accompanying certificate. The estimate for the Prussian Blue is between £8,000 - £10,000 and will be offered for sale on Monday 22nd September 2014
