A carved block of wood used as a doorstop in a Hertfordshire cottage for more than 40 years is expected to fetch around £100,000 when it is auctioned this afternoon.
The carving's owners were surprised to discover that it is, in fact, a rare Chinese pot from the 18th or 19th century.
Originally it would have been used to store calligraphers' brushes.
The auction is due to take place at Stansted Mountfitchet in Essex this afternoon.
