Henry V and the City of London's scepter.

For the first time in 600 years, a sceptre King Henry V gave to the City of London in gratitude for its support in the Hundred Years’ War will go on public display. The City of London helped finance the Battle of Agincourt, loaning Henry 10,000 marks (about three million pounds in today’s money). After Henry’s forces won so decisive a victory against the flower of French chivalry arrayed in much greater numbers against them on October 25th, 1415, the king had the sceptre made and presented it to the city as a thank you gift.
