Those looking to obtain accurate antique valuations might want to note details of a rare Chinese stamp auction set to take place in Hong Kong.
Interasia Auctions is staging the event, where 2,200 lots will give bidders the chance to pick up a bargain or two, as reported by the Independent.
Among the pieces up for grabs is the 1897 Red Revenue Small 2c Green Surcharge, which is expected to fetch as much as HK$10 million (£826,000).
The publication suggests this is known by many to be the most valuable Chinese stamp in existence.
In fact, there are only nine Red Revenue stamps available anywhere - and two of them are to be found in Beijing's China National Postal Museum.
Elsewhere, the Burton Mail recently reported that a damaged Chinese vase owned by a family in Derbyshire went for £10,600 at auction.
This was more than 30 times greater than its estimated worth prior to the sale.
