Circular wood. 3 1/8" diameter, the top with portrait of the King surrounded by GEORGE III BORN 4 JUNE 1738 / COMPLETED THE 50 YEARS OF HIS REIGN 25TH OCT. 1810. The same portrait used on other jubilee souvenirs including medallions. The top of this box executed in coin or medallion die struck precision. The inside with tortoise shell liner. The base with compass work. Unsure how this was produced and our research provided a wealth of jubilee material, but none matching this. Fine patina with cracks to the top.
