A bar of chocolate that is more than a century old is among items set to be sold at auction in the United Kingdom on September 24. 

The lot, which includes a box of Rowntree chocolate dating from 1900, features an image of Queen Victoria on the lid, reported news agency SWNS. 

Queen Victoria reigned as queen from 1837 until her death on Jan. 22, 1901.

In 1988, Rowntree's was purchased by Nestle, says the company's website.
