Paul Coleman from the Weekend Wanderers Detecting Club discovered more than 5,000 coins buried inside a lead bucket two feet under a field near Aylesbury. The hoard contains specimens dating back to the 11th Century - the late Anglo Saxon, early Norman period.
My bad....I just read the 1st part of the thread title..."large hordes of 11th century". I assumed the Turks were invading again.
