I thought that they were all given to buildings, like churches and cathedrals, to put in their foundations?! Ah yes I'm right - there's an informative article on it here. Plus there's this from another site - "Three of the 1933 pennies were known to have been placed under foundation stones of buildings. One is a building belonging to The University of London in Bloomsbury, two others were under churches in the Ripon diocese in Yorkshire. In September 1970, the Church of St. Cross at Middleton near Leeds was damaged by thieves who managed to remove and steal the 1933 penny buried under its cornerstone. As a precaution, the other church removed its coin, and sold it by auction at Sotheby's on the 24th November 1972. Over the years we have been coin dealers we have had many people tell us about 1933 pennies they have found. Most of these turn out to be Australian, British West Africa, Jersey, or Irish pennies, and their owners, usually victims of their own wishful thinking, omit to mention the fact that they are not British pennies."
