The HMS Glasgow Error is a 6d postage stamp error produced by the Falkland Islands in 1964. It commemorates the 50th anniversary of the 1914 Battle of the Falkland Islands.
The design error featured the incorrect ship, HMS Glasgow, instead of HMS Kent which should have been used. Apparently one sheet was sent to a stamp dealer in the United States who did not notice the mistake. It is believed that only the one sheet of 60 stamps was produced and only 17 stamps have been recorded.
One was sold in 2004 from the Sir Gawaine Baillie collection for £24,000 and another example was sold in December 2006 for £30,555. This should be one of the great stamps of QEII British Commonwealth.
