Two metal commemorative plates purchased from the shop inside Buckingham Palace, UK. One is a reproduction of a plate made to commemorate the 1851 London World's Fair, which was used at London's Guildhall. The other is a reproduction of a plate used at the opening ceremony of the Coal Exchange in 1849. The British Royal Coat of Arms is depicted in the center, and the surroundings are decorated with cobalt blue and gold. Diameter: 26 cm, Height: Approximately 1 cm They were purchased new and are unused, but there are some areas where the gold coloring has slightly discolored due to long-term storage, so they are listed as "near new." They appear black in the photos due to the lighting.
